Changing Ecosystems
100
This is the ability to make things move or change.
What is Energy?
100
Organisms that eat both plants and animals.
What is an omnivore?
100
This is a group of living things that can mate with each other and produce offspring.
What is a species?
100
This is a type of symbiotic relationship where only one species benefits and the other is not helped or hurt.
What is commensalism?
100
This is a place where a living thing is found naturally.
What is a habitat?
200
These organisms use the energy from sunlight to produce their own food. All plants are these.
What is a producer?
200
The process where plants use the sun's energy to change water and carbon dioxide into sugar.
What is Photosynthesis?
200
These are animals that hunt and kill other animals for food.
What is a predator?
200
This is a type of symbiotic relationship where one species is helped and the other is harmed.
What is parasitism?
200
This is a release of a harmful substance into the environment.
What is pollution?
300
Any organism that gets energy by eating other organisms.
What is a consumer?
300
Organisms that survive by breaking down dead organisms or waste produced by living things.
What is a decomposer?
300
A species that is eaten by a predator.
What is a prey?
300
This is an organism that takes energy and nutrients from a second species called a host.
What is a parasite?
300
This is when a species that existed in the past does not exist any longer.
What is extinct?
400
Organisms that eat mainly plants.
What is an Herbivore?
400
This is a model that shows how energy moves from one organism to another.
What is a food chain?
400
This is a close relationship between two species.
What is symbiosis?
400
This is an organism that a parasite takes energy and nutrients from.
What is a host?
400
This is a species in danger of becoming extinct.
What is an endangered species?
500
Organisms that eat mainly other animals
What is a carnivore?
500
This is a model that shows connected food chains in an ecosystem.
What is a food web?
500
A symbiotic relationship where both species benefit.
What is mutualism?
500
The pilot fish travel with sharks. When a shark captures prey, the shark leaves small bits of food that it does not eat. Pilot fish feed on these scraps. The shark is not harmed because it would not have eaten the smaller scraps anyway. The pilot fish benefits by getting food to eat. This is an example of this type of symbiosis.
What is commensalism?
500
This is a species that is not native to an ecosystem and harms the ecosystem. It was not part of an ecosystem until someone brought it there.
What is an invasive species?
