Do caterpillars only live in forests? Explain
No, they can also live in grasslands and wetlands depending on the species.
What are some examples of habitats?
Forest, desert, grassland, wetland, marine.
Give an example of a herbivore.
Rabbit or deer.
What are trophic levels?
Producers (plants), primary consumers (herbivores), secondary consumers (carnivores or omnivores).
What could happen if a plant species goes extinct?
Primary consumers that depend on the plant may decrease, affecting the whole food chain.
What is the starting point of energy in a food web?
The Sun.
Name a carnivore in a forest ecosystem.
Fox or owl
Can a polar bear survive in a desert ecosystem? Why or why not?
No, because the habitat conditions are not suitable.
What are autotrophs?
Organisms that produce their own food using sunlight.
What type of consumer is a frog?
Secondary consumer (eats insects).
What role do small fish play in an ecosystem?
They are both predators (eating plankton) and prey (eaten by larger fish). Question: Why are decomposers important
Name three ecosystems where rabbits can live
Grassland, forest, and desert.
What role do mice play in the ecosystem?
Predators (eating seeds and insects) and prey (eaten by snakes, owls, and foxes).
Name a primary consumer in a desert ecosystem.
Grasshopper.
How are food webs different depending on the habitat?
Depending on the habitat, plants and animals create their unique connections.
How does pollution affect a food web?
It can harm plants and animals, breaking important links in the web.
Why are food webs more complex than food chains?
Food webs show multiple connections between organisms, while food chains show a single pathway of energy flow.
What is a habitat?
The area where an organism lives
What is biomass?
The amount of food energy available in living things at each level of a food chain.
What happens to the energy as it moves up the food chain?
It decreases because some energy is lost at each level.
Why are decomposers important?
They recycle nutrients from dead plants and animals back into the soil, helping new plants grow
How can a food chain be disrupted?
For example, if a top predator goes extinct, primary consumers may grow uncontrollably and deplete plants.
Give an example of a producer in a marine ecosystem.
Algae
How does energy flow in a food chain?
It starts from the Sun, goes to plants, and then moves up the chain as animals eat each other
