Food Chain/
Food Web
Food Web
This type of organism makes its own food using sunlight.
What is a producer?
A relationship where both species benefit.
What is mutualism?
Differences in traits within a population.
What is variation?
True or False
Instincts are inherited behaviors.
TRUE
A predator at the top of a food chain with no known natural predators.
What is an apex predator?
A deer that eats grass is this type of consumer.
What is a primary consumer?
A close relationship between different species.
What is symbiosis?
True or False
"Survival of the fittest” means the strongest organism always survives.
False
A child learning to ride a bike is this type of behavior.
What is learned behavior?
The study of interactions between organisms and their environment.
What is ecology?
This organism breaks down dead plants and animals and returns nutrients to the soil.
What is a decomposer?
A barnacle attaches to a whale. The barnacle benefits, but the whale is not affected.
What is commensalism?
Organisms better suited to their environment are more likely to do this.
survive and reproduce
A bird building a nest without being taught is an example of this type of behavior.
What is an innate behavior?
An ecosystem includes living organisms and these factors.
What are abiotic factors?
A carnivore that eats another carnivore is this type of consumer.
What is a tertiary consumer?
Two plants grow close together and both need sunlight, water, and space.
What is competition?
Why is reproduction important in natural selection?
Traits must be passed on to the next generation.
An adaptation that involves body features like color or shape.
👉 What is a physical trait?
What is a physical trait?
What might happen to the producers if secondary consumers are removed from a food web?
👉
Producers might decrease because of a increased in Primary consumer population.
Name one similarity and one difference between a food chain and a food web.
Similarity: both show energy transfer.
Difference: a chain shows one path; a web shows many paths.
A tapeworm lives inside a human and takes nutrients, making the human sick.
What is parasitism?
A population of beetles lives on brown soil. Some beetles are green and some are brown. Over time, birds eat more green beetles than brown beetles.
If this continues for many generations, what will happen to the green beetles, and why?
The green beetles may become very rare or go extinct because they are easier for predators to see. Since fewer green beetles survive and reproduce, their trait is not passed on. Over time, the green beetle population may disappear.
Why are learned behaviors NOT passed down to offspring?
They are gained through experience, not DNA/genes.
What will happen if decomposers disappear from an ecosystem?
Dead material will build up and nutrients will not return to the soil.
