Begin on Page 10Which of the following do you see? Explain why you think you see it.
EcosystemDecomposer HabitatWater cycle Biotic factors Abiotic factors
Ecosystem: a pond environment is a particular environment,
turtles,trees and grass are living things,
and rocks, water, and air are nonliving things that support these three living things
DecomposersThere aren’t any visible organisms breaking down dead plants or animals.
We do know they are there but we can’t count them because we don’t see them. The question asked us which do we see.
Habitat:
The water is the physical place the turtles live in
and the pond shore is the physical place the trees and grass live.
Water cycle:
Collected water, like a pond, is part of the water cycle but we aren’t able to see the movement of water through the environment.
Biotic Factors:The turtle, trees and grass are living things
Abiotic Factors:The rocks, soil, water, and air are nonliving things
WE CAN START AT ANY STEP BECAUSE A CYCLE IS STEPS THAT REPEAT!!!!!!
Precipitation: water drops fall because gravity pulls them
Run off / Collection: Water moves downhill, soaks into the ground, or collects in bodies like lakes and ponds
Evaporation: Water becomes a gas
Condensation: Water turns back to liquid drops and clings to particles in the air
They show food energy flowing through an ecosystem
They show the relationship between producers and consumers
It shows the amount of energy passed up to each level
It shows there is less food energy available as one moves up the pyramid. Energy decreases.
A niche is a role that an organism has within a habitat
A habitat is where the organism carries out its niche-where it “does its thing”.
An ecosystem contains a community. The community is only the LIVING part of the ecosystem. There is also a nonliving part in an ecosystem.
