Energy Roles in an Ecosystem
An organism that can make its own food.
What is a producer?
When one organism eats another to obtain energy.
What is food chain?
Human activities may effect the balance of an ecosystem.
How might an ecosystem change?
Evaporation, condensation, and precipitation.
What makes up the watercycle?
An essential building block in the bodies of living things.
What is carbon?
An organism that obtains energy by feeding on other organisms.
What is a consumer?
Overlapping food chains in an ecosystem.
What is a food web?
There's more carbon dioxide in the atmosphere.
What happens when we cut down forests?
The process by which molecules of liquid water absorb energy and change to gas.
What is evaporation?
Consumers eat producers, release carbon dioxide and water into the environment, decomposers return carbon molecules to the soil and carbon dioxide into the air.
What is the carbon cycle?
Consumers that eat both plants and animals.
What is an omnivore?
Fox, grasshopper, plants.
What is the order of a food chain?
Animals have trouble reproducing.
What happens when humans use chemicals on farm land?
The process by which gas changes to liquid.
What is condensation?
Producers release oxygen as a part of photosynthesis.
What is the oxygen cycle?
Consumers that eat only plants and only animals.
What is a herbivore and a carnivore?
The amount of energy that moves from one feeding level to another in a food web.
What is a energy pyramid?
The fish populations suffer.
What happens when the fish species are overfished?
Rain, snow, sleet, or hail.
What is precipitation?
Human activities affect levels of carbon and oxygen in the atmosphere.
What is the human impact?
A scavenger and a decomposer.
What are two ways dead organisms are recycled in the ecosystem?
The most energy available on a food pyramid.
What is the producer level?
The advance of desert like conditions in an area once fertile.
What is desertification?
Liquid that runs off land into a body of water.
What is surface runoff?
The process of changing free nitrogen into a usable form of nitrogen.
What is nitrogen fixation?
