organism - any individual living thing.

(Human)
population - all of the individuals of a species that live in the same area.

(Other human)
community - collection of all of the different populations that live in one area.

(Different types of trees, leafs, and etc)
ecosystem - collection of organisms and nonliving things, such as climate, soil, water, and rocks, in an area.

(part of school tree)

biome - regional or global community of organisms characterized by the climate conditions and plant communities that thrive there. (IMG_1809)

(whole school forest)

biodiversity- variety of life within an area.

(different type of leafs and trees)

keystone species and explain how a beaver is an example (with labelled picture)

Beavers are a keystone species because they live near rivers and they chunk off trees and build their houses. By doing such actions those trees are like dams therefore, rivers will flood and become a bigger river.

Producer - organism that obtains its energy from abiotic sources, such as sunlight or inorganic chemicals.
Autotroph - organism that obtains its energy from abiotic sources, such as sunlight or inorganic chemicals. (IMG_1778)

(tiny leafs)

Consumer - organism that obtains its energy and nutrients by consuming other organisms.
Heterotroph - organism that obtains its energy and nutrients by eating other organisms. (IMG_1873)

(Beatles )

Food chain - model that links organisms by their feeding relationships.

Herbivore - organism that eats only plants.

(Koala)

carnivore - organism that obtains energy by eating only animals.

(Cheetah)

omnivores - organism that eats both plants and animals. (IMG_1877)

(Human)

detritivores - organism that eats dead organic matter.
decomposers - detritivore that break down organic matter into simpler compounds, returning nutrients back into an ecosystem.

detritivores: flies

decomposers: dead warm

specialist - consumer that eats only one type of organism.

(Koala)

Trophic levels (primary, secondary and tertiary) - level of nourishment in a food chain.

Food web - model that shows the complex network of feeding relationships within an ecosystem.

biomass - total dry mass of all organisms in a given area. (IMG_1910)

(Bug...i don't know what this is!)

energy pyramid - diagram that compares energy used by producers, primary consumers, and other tropic levels.
