Abstract
Every individuals or organisms dwell in a place where well suited for their growth and development, survival and reproduction. When changes happened to their environment expected changes will also be observed and adaptation mechanisms are produced. This study focuses on the responses of modular and solitary organisms under their normal environmental condition and on their disturbed or changed environment. The study further focuses on how long the unitary organisms respond to certain disturbances and how modular organisms respond to lessen the effect of environmental changes happening on their surroundings. Ant’s behavior in three different activities under normal conditions was observed and their response also under disturbed conditions was also observed by inducing commotion to their environment. Moreover, ants were also tested on which food they are most likely be attracted, results showed that they prefer sweeter food sources rather than the salty ones. On the other hand, two sets of modular organisms were subjected to environmental changes, a set for the sun-loving plants (Cyperus and Althernanthera) and shade-tolerant plants (Zebrina and Talinum) were interchangeably exposed to each other’s environment. Results generally showed that when plants are put into an environment where they are not used to, they tend to grow poorly and vice versa. But some developed mechanisms to lessen the impact of the stress applied to them. In conclusion, unitary animals adjust faster than modular organism because they communicate and work with each other but modular organisms have unique ways of

    It is hypothesized that as plants in small spaces compete for space, the plants compensate by reducing individual stem weight and frequency of bud formation as density increases. This would be intraspecific competition. A factor is density-dependent when it kills more of a population at higher densities and less at lower densities (Stilling 2002). The factor of competition between individual plants of the same species would be considered density dependent.…

    There are many factors that account for the changes to the vegetation over time within ecosystems in the British Isles, such as human activity, climate, soil, light availability and intensity and natural disasters. The characteristics of the vegetation that are influenced by these factors are height, distribution, variety of species, adaptations and density of the vegetation. Some of these factors have relatively little influence on the succession development, whereas others have a dramatic influence over a long period of time, such as human activity. These factors, over time, result in the progression of a succession until the climatic climax vegetation is reached. However, sometimes these factors can mean that a plagioclimax is reached, as they prevent the succession from progressing any further and the climatic climax vegetation is never achieved, which in the UK are Oak, Hawthorne and Birch trees. This succession results in the development of an ecosystem. An ecosystem is a dynamic, stable environment which is composed of interacting and functioning biotic and abiotic components and can be of any size. There can be composed of variety of successions, such as lithoseres in grassland and woodland areas for example the Isle of Aaron, psamoseres along the coastline or small scale urban successions in urbanised areas.…

    By Helen Ying © 2013 Biology Notes – HSC Course 2013 MODULE 9.3 – BLUEPRINT OF LIFE 1. Outline the impact on the evolution of plants and animals of: a. Changes in physical conditions in the environment o Rising and falling sea levels – land and ice bridges across continents have affected distribution and therefore evolution when these bridges disappeared and populations were isolated from the main population. o Fossil evidence indicates mass extinctions resulting from changes in the physical environment e.g. dinosaur extinction from meteor. o Movement of continents. As Australia moved north, it became drier and plants and animals needed to adapt to these new conditions. b. Changes in chemical conditions in the environment o Original anoxic environment. As primitive organisms metabolised, carbon dioxide was released. Over millions of years, carbon dioxide accumulated and at some stage, organisms capable of using carbon dioxide in photosynthesis evolved and became dominant. Oxygen was then released as a product of photosynthesis, and oxygen-using organisms became dominant. c. Competition for resources o During the Cretaceous period, mammals were limited to the niches in which they originally evolved because the world was dominated by dinosaurs. When the dinosaurs died, the mammals were able to populate larger areas of the world as they had few competitors. As they populated these different areas, they evolved into new species to adapt to these new conditions. o Long-term competition usually results in one of the species dying out or evolution of one of the competing species so that they can occupy a different environment.  Organisms alive today have all arisen from simpler organisms that existed millions of years ago.  Evolution is the change in living organisms over many generations.  Changes in the environment of living organisms can lead to the…

    Since there are large amounts of rainfall in the temperate forest regions there is a wide variety of plant life in the temperate forests. There plants can be considered the producers for this biome and include maple trees, walnut trees, birch trees, dogwoods, redbuds, azaleas, mountain laurel, huckleberries, blue bead lily, indian cucumber, linchens, and mosses. These different plants are divided into several layers including the forest canopy, small tree, shrubs, herbs, and floor tier.…

    A savanna, or savannah, is a grassland ecosystem characterized by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses.[1][2][3] The oak savanna is a common type of savanna in the Northern Hemisphere. Some classification systems[which?] also recognize a grassland savanna from which trees are absent.[4] This article deals only with savanna under the common definition of a grassy woodland with a significant woody plant component.…

    In Dunedin there are many different plants and trees scattered across different areas. This can be a forest, flower fields, grasslands, or a mix up. How did they get there and how long will they survive there? The aim of todays study is to look at the mix of habitats down by the Water of Leith, and see if the riverside environment resembles the theory about plant strategies and vegetation. The theory roughly states that if conditions allow it, trees will dominate a plant community, and that in more disturbed areas, smaller, fast growing plants with high seed mobility will prosper.…

    Charles Robert Darwin is most well-known for his book ‘On the Origin of Species’ this book contains detailed argument, evidence and ideas on his theory of evolution by natural selection. Despite how much this has influenced today’s research Darwin always wanted more evidence, this was because his theory was controversial at the time. However, it is now a highly regarded concept which is widely accepted in life sciences. On Darwin’s famous voyage aboard the HMS Beagle around the world he studied and worked on geology, botany, zoology and scientific research. This essay will explore Darwin’s research and contribution to science through insectivorous plants, which is where Darwin believed to be a link. Plants are often seen as immobile and unresponsive but Darwin saw them as ‘active with interesting behaviour’. Charles Darwin actually produced the first well-known book on carnivorous plants (Insectivorous Plants, 1875) and therefore offered the initial study into the topic. In this book he examines many species and identifies why they must become carnivorous to survive, and individual adaptations to each species. Looking at how the plants reacted to certain stimuli to understand its evolutionary reasoning for their adaptations and surviving environmental conditions. These include heat, nitrogenous fluids and nutrition. Another major modification that these plants have is the ability to move rapidly or faster than other plant types. Darwin contributed in so many ways to this area of botany which this essay will demonstrate.…

    Born in November 1904 in Jaipur (Rajasthan) Panchanan Maheshwari rose to become one of the most distinguished botanists not only of India but of the entire world. He moved to Allahabad for higher education where he obtained his D.Sc. During his college days, he was inspired by Dr W. Dudgeon, an American missionary teacher, to develop interest in Botany and especially morphology. His teacher once expressed that if his student progresses ahead of him, it will give him a great satisfaction. These words encouraged Panchanan to enquire what he could do for his teacher in return.…
