A diagram that shows the amount of energy that moves from one feeding level to another in a food web.
What is an energy pyramid.
100
What is the source of energy for all ecosystems?
What is the sun.
100
Name three examples of limiting factors.
Food, water, weather, shelter and space are some of the limiting factors that we learned about. Answers may vary.
100
A blind shrimp digs a home for a goby fish. The goby guides the shrimp. Name the symbiotic relationship.
What is commensalism?
100
In mutualism name two benefits that the relationship provides.
Clean, protection, shelter, and food.
200
An environmental factor that causes a population to decrease
What is limiting factor?
200
How much energy passes from one level to the other? How much is used for its life processes?
10% passed from one level to another and 90% is used for life processes.
200
Give two examples of limiting factors for fish.
Answers could vary. Food, space, water,and weather.
200
A vampire bat bites a cow and drinks its blood. The cow is harmed. Name the symbiotic relationship.
What is parasitism?
200
What are the two types of organisms that parasitism must include? Which one benefits?
What is parasite and host. The parasite is the one that benefits in this relationship.
300
The largest population that an area can support.
What is carrying capacity.
300
What happens to the energy that is not passed? Give 3 examples of how the energy could be used.
It is used for life processes. Examples can vary.
300
How would a drought affect this food chain? grass->grasshopper->frog
The grass would not grow well because of the lack of water, which means the grasshopper would have nothing to eat and there would be no grasshoppers for the frog to eat.
300
A bird builds a nest in a tree. The tree is not harmed. Name the symbiosis relationship.
What is commensalism?
300
Which level of a energy pyramid has the least amount of available energy? Which has the most? Explain.
The top level has the least available energy because it depends on other organisms for food. The bottom level has the most available energy because it makes it own food.
400
Is a close relationship between two types of species that benefit at least one of the species.
What is symbiosis.
400
What does the shape of the pyramid have to do with the amount of energy available at each level?
As the pyramid goes up, the energy available decreases.
400
How do non-native species harm the ecosystem?
They take over the ecosystem because they have no natural predators.
400
Why doesn't the parasite kill the host in a parasitic relationship?
Because if the parasite killed the host, it would have to find a new host or die of starvation.
400
A giraffe eats 20 kilograms of leaves a day. The only tree in the area produces 180 kilograms of leaves a day while remaining healthy. What is the carrying capacity of the giraffes in this area?
What is 9 giraffes?
500
An introduced, alien, exotic, non-indigenous, or non-native species, or simply an introduction, is a species living outside its native distributional range, which has arrived there by human activity, either deliberate or accidental.
What is non native species
500
What process do the plants use to obtain energy from the sun?
What is photosynthesis.
500
grass-> rabbit -> owl What are two changes that would happen if the rabbits died?
The grass would overpopulate because no one would be eating it. The owl would either go to another ecosystem for more resources or they would die because they would have no rabbits to eat
500
Why is commensalism rare in nature?
Not very common in nature because the species are usually either helped or harmed a little by any interaction.
500
Name each type of symbiotic relationship, explain how the two organisms are affected?
Parasitism- one is harmed and one benefits Mutualism- both benefits Commensalism- one benefits and one is unharmed.
