is the study of the interactions among living things and their surroundings

is a group of different species that live together in one area, such as turtles, birds, fish and plants

includes all the organisms as well as the climate, soil, water, rocks and other nonliving things in a given area

is a major regional or global community of organisms

is an organism that gets their energy from nonliving resources, meaning they make their own food

producers are also called autotrophs; prefix -auto mean self ; suffix -troph means nourishment

is an organism that get their energy by eating other living or once-living resources.

consumers are also called heterotrophs; prefix -hetero means different

is the process by which an organism forms carbohydrates using chemicals rather than light, as an energy source

is a sequence that links species by their feeding relationships

are organisms that eat only plants, such as desert cottontails

are organisms that only eat animals, such as Harris's Hawks eat desert cottontails

are organisms that eat both plants and animals, such as Kangaroo rats eat both seeds and insects

are organisms that eat dead organic matter or detritus, such as a millipede that feeds on particles of detritus

are detritivores that break down organic matter into simpler compounds, such as microorganisms and fungi

are consumers that have a varying diet

are levels of nourishment in a food chain

is a model that shows the complex network of feeding relationships and the flow of energy within and sometimes beyond an ecosystem
