Camren Allen Concept Check 1.1: 1.) A biosphere has an ecosystem that consists of all living things in an area. An ecosystem consists of communities which hold organisms that live in a specific area. A community consists of populations of all the individual organisms in a specific area. A population consists of living things called organisms. Organisms break down into organs and organ systems which are more complex parts of organisms. Organs and Organ Systems are created by tissues which is

each cell. Other things in nature that might affect the growth rate of plant cells are sunlight‚ water‚ space‚ temperature‚ nutrients‚ bacteria‚ weeds‚ allelopathy‚ insects‚ soil‚ etc. In areas where there are very few plants growing‚ the following abiotic factors may be affecting the plant’s ability to thrive as well as the rate of mitosis: light‚ water‚ soil‚ nutrients‚ space and temperature. The few plants living are competing for sunlight‚ water‚ and nutrients a plant needs to perform photosynthesis

is a complex ecosystem which is predominantly composed of trees‚ shrubs and is usually a closed canopy. Forests are storehouses of a large variety of life forms such as plants‚ mammals‚ birds‚ insects and reptiles etc. Also the forests have abundant microorganisms and fungi‚ which do the important work of decomposing dead organic matter thereby enriching the soil. Nearly 4billion hectares of forest cover the earth’s surface‚ roughly 30 percent of its total land area.The forest ecosystem has two components-

I’m an penguin and I live in the polar ice biome. We are birds with black and white feathers. Unlike most birds we don’t fly. We spend about 75% of our time underwater‚ searching for food in the ocean. We are one of about 40 species of flightless birds. We are known for their white bellies and dark-colored backs and wings. Our body is designed for swimming‚ and includes tapering at both ends of the body for hydrodynamics‚ paddle-like wings

is defined as the biological and chemical changes a body undergoes after death. It is the decay of tissues and structures. There are two types of decomposition: abiotic and biotic. Abiotic decomposition is defined as the degradation of a substance by chemical or physical processes; such as hydrolysis‚ reduction‚ or oxidation. Biotic decomposition is the metabolic breakdown of materials into simpler components by living organisms. This is typically done by microorganisms. “The [decomposition]

“With reference to at least ONE ecosystem you have studied‚ explain the biophysical interactions which lead to diverse ecosystems and their functioning” An ecosystem is the interaction between biotic and a biotic features. Each element of an ecosystem relies on one another in order to maintain the ecosystem. The interacting biophysical elements include the atmosphere‚ lithosphere‚ hydrosphere and biosphere. This is shown at the Towra Point Estuarine Wetlands ecosystem‚ located on the southern shores

Key Terms (Bio3_Exam3) Amniote – A group of organisms including reptiles‚ mammals and birds whose offspring develop initially internally. Body Cavity – A fluid or air filled space located between the digestive tract and the outer body wall. Also known as a coelom. Body Plan – Particular set of morphological and developmental traits integrated into a functional whole. Bottom–up Regulation – The study of how applying a pressure to the base of a food chain affects the links above it. Carnivorous

Really Change Rivers? Wolves can really change rivers. Wolves bring the benefit to the ecosystem by killing and eating other animals. Unfortunately‚ people realize the fact only until the absence of these apex predators‚ also known as alpha predators. Apex predators are predators with no natural predators of their own and resides at the top of their food chain. Many people think that predators bring harm to the ecosystem by killing and eating other animals‚ but they don’t realize the benefit they bring

of invasive species into new environments is a problem that plagues the entire planet. Humans have been moving species around the world and introducing them into new environment for millennia. Many introduced species become invasive‚ disrupting ecosystems and threatening the survival of other species‚ sometimes driving them to extinction. Some invasive species‚ including some insects‚ seem to thrive particularly well in already degraded environments. After habitat destruction‚ the issue of invasive
