Ecosystems

Individual (one)

Population (a group of the same organisms)

Community (many populations living together)

Ecosystem (biotic and abiotic working together)

Biosphere (all the world's ecosystems)

Biotic- Bio(living) living things (plants/animals)

Abiotic- A(no/not) Bio(living) NONLiving (soil, rocks, water)

Plants need energy to make their food (photosynthesis)

Animals need the sun to make the food they eat grow so they will have food to eat (Cellular Respiration)

CONSUMERS (have to eat their food) depend on PRODUCERS (plants) for energy

Heterotroph (eat different things)

SECONDARY CONSUMERS (Eat Primary consumers). (birds, hyena, snake)

TERTIARY CONSUMERS (eat secondary consumers). (lions, Cheetahs, owls)

CARNIVORES- Eat only meat

10% of the energy is transferred from one level to the next.

The organisms at the TOP of the food chain receive the LEAST amount of energy

Ex. Lions sleep most of the day

ex. If a wildfire destroys all the grass on the prairies in Africa the Lions will be affected as well as all organisms in that food chain.

No grass, no food for gazelle , no food for lions
