Science (ecosystem) Flashcards
What is an omnivore
An omnivore is a animal that was born to eat plants and animals
What is a carnivore
a carnivore is an animal born to eat only meat
what is a herbivore
a herbivore is a animal born to eat only plants
What are decomposers
Decomposers are living organisms that decompose dead organisms or waste some examples of a decomposer are fungi, flies and bacteria decomposers are also known as reducers
what is law 1 of thermodynamics
energy cannot be created nor destroyed only transformed from one form to another
what is law 2 of thermodynamics
when energy is transformed some of it is lost about 10% is passed on and the 90% gets lost if there is to much energy in an animal it gets excreted
what is a producer
a producer is a living thing that uses abiotic elements to survive like the sun and water they get their energy by photosynthesis
what is photosynthesis
photosynthesis happens when there is carbon dioxide and the sun in any ecosystem when it hits plants that is how they get their energy
what is consumers
consumers are any living thing that cannot make their own energy so they eat plants and animals the 3 types of consumers are herbivores omnivores and carnivores
what is a primary consumer
a primary consumer is an animal that gets eaten by other animals all primary consumers are all herbivores which makes them bottom of the food pyramid some examples of primary consumers are bunnies grasshoppers and deer
what is a secondary consumer
a secondary consumer is an animal that gets eaten by other animals but also eats smaller animals examples are small birds and shrew
what is a tertiary consumer
tertiary consumers can still be eaten but they eat bigger animals some examples are snakes, bears and foxes
What is a apex predator
a apex predator is an animal that will not get eaten by anything bigger than themselves that is why there at the top of the food chain some examples are lions and polar bears
what are abiotic elements
abiotic elements are things that are not alive and interacted with biotic elements some examples are rocks, dirt, water, wind and the sun
what are biotic elements
biotic elements are any living thing like tree, leaves, grass, worms, bacteria, wolfs, deer, lions, shrew, ants, bush, fungi, and bunny
