How can a food chain be disrupted?
For example, if a top predator goes extinct, primary consumers may grow uncontrollably and deplete plants.
Can a polar bear survive in a desert ecosystem? Why or why not?
No, because the habitat conditions are not suitable.
How are food webs different depending on the habitat?
Depending on the habitat, plants and animals create their unique connections.
What is a habitat?
The area where an organism lives
Why are decomposers important?
They recycle nutrients from dead plants and animals back into the soil, helping new plants grow
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
What are autotrophs?
Organisms that produce their own food using sunlight.
What are trophic levels?
Producers (plants), primary consumers (herbivores), secondary consumers (carnivores or omnivores).
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
Name three ecosystems where rabbits can live
Grassland, forest, and desert.
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.
What is the starting point of energy in a food web?
The Sun.
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 happens to the energy as it moves up the food chain?
It decreases because some energy is lost at each level.
Give an example of a producer in a marine ecosystem.
Algae
