How does water affect what kinds of organisms live in an environment?
If there isn't much water than organisms that don't need much water will live in the environment. If there is a lot of water than organisms that can survive with a lot of water will live in the environment.

community
200
All of the abiotic and biotic parts of the environment interacting together in one area.
What is an ecosystem.

Producers are plants that get their energy from the sun and the soil. This is called ________________. What organelle do plants have in their cells that collect energy from the sun?
What is photosynthesis. Chloroplasts

The study of the interactions of living organisms with one another and with their environment.
What is ecology.
300
The part of the Earth where life exists.
What is the biosphere.
300
_______________ get their energy from eating producers. An example are elk.
What are herbivores or primary consumers.
300
This shows the loss of energy as energy passes through the food chain.
What is an energy pyramid.
300
Name three ways that the carrying capacity of elk decrease in an environment?
Drought - loss of water and plants Increase in predators Humans building - lose of space

The largest population that an environment can support at any given time.
What is carrying capacity.

adaptation camouflage sharp or flat teeth thick fur poison
500
All the populations of species that interact in one area. Alligators, birds, salamanders.
What is a community.
500
Water, temperature, rocks and soil are __________ parts of the environment.
What is abiotic.
500
Humans are _______________. We eat producers and meat. Herbivores, carnivores and omnivores are all examples of ________________. The scientific word for this is also _________________.
What is a omnivore. consumers heterotrophs
500
A resource that is not often found in an environment. It can make the population smaller.
What is a limiting factor.

Describe the energy path in any food web or chain.
The sun is the source of all energy. Plants are producers. This means they gather their energy from the sun and turn it into food, which is sugar. This is called photosynthesis. The primary consumers, which are herbivores get their energy from producers. Secondary consumers get their energy from primary consumers. Tertiary consumers receive their energy from secondary consumers. As energy gets passed through the food chain/web energy is lost.
