Parts and Workings
Abiotic and Biotic
This is the place in an ecosystem where an organism lives.
Habitat
This is what the arrows in a food chain represent.
The flow of energy.
These two things cause ecosystems to change.
Natural events and people
This is another name for non-living things in an ecosystem.
Abiotic factors
These are organisms that eat only producers.
Herbivores
These organisms make their own food using energy from the sun.
Producers
This is how you make a food web.
Multiple food chains put together.
This is what happens when organisms in an ecosystem fight for the same resources (such as food and water).
Competition
This is what happens when trees are cut down to make roads or rooms for buildings.
Deforestation
These are the three levels of interaction within an ecosystem.
Abiotic to Abiotic
Biotic to Biotic
Abiotic to Biotic (or Biotic to Abiotic)
These are the three types of organisms in an ecosystem.
Producers, Consumers, Decomposers
This is the starting point of all energy.
The sun.
This is what we call a species when the last of its members dies.
Extinct
These are organisms that eat herbivores and omnivores.
Carnivores
These are the three types of consumers in an ecosystem.
Carnivores, Herbivores, Omnivores
This is made up by all the members of a single species in an ecosystem.
Population
This is the direction that arrows point in a food chain/web. (Hint: from what to what?)
From what is being eaten to what is eating it.
This is the process by which an individual responds to change in an ecosystem.
Accommodation
This means too many individuals living in an area.
Overpopulation
This is an organism that eat only producers.
Herbivore
This is made up of multiple populations within an ecosystem.
Community
This is why decomposers are often left off of food chains.
They are part of every step.
These are four things that people do to change ecosystems???
Pollution, Deforestation,
These are organisms that eat producers and consumers.
Omnivores
