Producers and Consumers
These organisms use sunlight to make their own food.
What are producers?
The first step in a food chain, often a plant or algae.
What is a producer?
This gas is produced by plants during photosynthesis.
What is oxygen?
These animals eat only plants.
What are herbivores?
These non-native species can harm an ecosystem by outcompeting native species.
What are invasive species?
Organisms like mushrooms that break down dead plants and animals for food.
What are decomposers?
These organisms eat producers.
What are herbivores?
This gas is absorbed by plants to help them make food.
What is carbon dioxide?
These animals eat only meat.
What are carnivores?
The removal of this species from an ecosystem can cause big changes, often harming it.
What is a keystone species?
These animals must consume other organisms for energy.
What are consumers?
A food chain shows this, connecting different organisms based on what eats what.
What is the movement of matter and energy?
When animals breathe in oxygen, they release this gas.
What is carbon dioxide?
Bears and raccoons are examples of this type of animal, eating both plants and animals.
What are omnivores?
The sudden decline of a species could lead to this, disrupting an entire ecosystem.
What is an ecosystem collapse?
This process allows plants to convert sunlight into food.
What is photosynthesis?
This is a system that shows how all organisms in an ecosystem are interconnected by their feeding relationships.
What is a food web?
The process of photosynthesis takes in this gas and releases this other.
What are carbon dioxide and oxygen?
A fox hunting and eating a rabbit is an example of this relationship.
What is being a predator?
This is the process by which an area becomes overrun with non-native species, often causing damage.
What is ecological disruption?
Plants and algae are examples of this type of producer.
What are autotrophs?
A lion is an example of this type of organism, which eats other animals.
What is a predator?
The balance of oxygen and carbon dioxide in an ecosystem is important for these two cycles.
What are the carbon and oxygen cycles?
These animals are usually at the top of the food chain and have no natural predators.
What are apex predators?
This invasive species is the worst one in the United States in the past century.
What is the lantern fly?
