Ecosystems - Ecosystems Flashcards
What is an ecosystem?
An ecosystem is a community of organisms living together and interacting with each other and their surrounding environment.
Every organism in a food chain is one of three things. What are they?
Producers, consumers, decomposers.
Where can producers be found in a food chain?
In the first tropic level.
How do producers get their energy?
Producers use water, carbon dioxide and sunlight to create chemical energy. This process is called photosynthesis.
Why are producers important?
Producers are important because they provide energy to the consumers in the food chain, who are unable to photosynthesise. They also release oxygen, which most animals need to live.
What are some examples of producers?
Examples of producers include grass, trees, flowers, and any plant.
What are consumers?
Consumers are organisms that feed on other organisms to abstain energy, as they are unable to create their own energy.
What are the four main types of consumers?
Herbivores (primary consumers), carnivores and omnivores (secondary and tertiary consumers) and detritivores.
What are some examples of primary consumers?
Rabbits, mice, and herbivores.
What are some examples of secondary consumers?
Lizards, foxes, medium-sized fish.
What are some examples of tertiary consumers?
Sharks, snakes, humans.
What are some examples of detritivores?
Dung beetles, earthworms, millipedes.
Where can primary consumers be found in a food chain?
On the second trophic level.
Where can secondary consumers be found on a food chain?
On the third trophic level.
Where can tertiary consumers be found on a food chain?
On the fourth trophic level.
