Biotic and Abiotic Factors
What are living things called?
biotic factors
What is a food chain?
A sequence showing how energy is transferred from one organism to another.
What do we call organisms that make their own food?
producers
What do we call animals that eat plants?
herbivores
What is a prey?
An animal that is hunted and eaten by predators.
What are nonliving things called?
abiotic factors
What is a food web?
A complex network of interconnected food chains.
What do we call animals that rely on other organisms for food??
consumers
What do we call animals that eat both plants and animals?
omnivores
What happens to the prey population if the predator population increases?
They prey population may decrease
Give an example of a biotic factor
Ex: plants, animals, fungi, etc.
How does energy flow in a food chain?
From producers to consumers in a linear path.
What role do decomposers play in an ecosystem?
They break down dead organic matter, returning nutrients to the soil.
Give an example of a carnivore.
tiger, lion, etc
What is a predator?
An animal that hunts and eats other animals.
Why are abiotic factors important for ecosystems?
They provide essential conditions for living things to survive.
What is the difference between a food chain and a food web?
A food chain is a single pathway; a food web includes multiple pathways.
Name one example of a decomposer.
fungi, worms, bacteria
Name one example of an omnivore.
bear, human, etc
How do predators help control prey populations?
they keep the prey population from becoming too large
How can changes in abiotic factors affect living things?
How can changes in abiotic factors affect living things?
Why is a food web more realistic than a food chain?
It shows the multiple feeding relationships in an ecosystem.
Why are producers important to an ecosystem?
they provide energy for all other organisms
How do herbivores affect plant life?
They help control plant populations and promote growth.
Give an example of a predator-prey relationship.
