What is an energy pyramid?
A triangular diagram that shows the amount of energy moving from one feeding level to another. It also shows an ecosystem's loss of energy.
100
What is a food chain?
A diagram that shows one way energy can move through an ecosystem.
100
How is energy transferred to a organism?
By eating another organism or producer.
100
What is predation?
An interaction in which one organism kills another for food.
100
What is a niche?
A niche is a role of an organism in its habitat.
200
What are the levels of the energy pyramid, from largest to smallest?
Producers, primary consumers, secondary consumers, tertiary consumers.
200
How is a food web better than a food chain?
Food webs are more realistic because they show more possible things a predator can eat.
200
Name all the energy roles organisms play in an ecosystem in order.
Producer, Consumer, Decomposer.
200
What are the two organisms in a predation relationship called? Define them.
The two organisms are the predator and the prey. The predator is the organism that does the killing, while the prey is the organism being killed.
200
What is competition?
It is the struggle between organisms to survive as they attempt to use the same limited resource.
300
What is the difference between an energy pyramid and a food web?
An energy pyramid shows the amount of energy moving from one feeding level to another while a food web shows all the feeding relationships between organisms in an ecosystem.
300
What is a primary consumer?
The consumer that gets its energy from the producer.
300
Why does energy become less and less when it goes up the consumer category?
Because the energy is used up overtime by lower levels.
300
What is an example of predation stated in the packet?
The shark's relationship with the albatross is an example of predation. In this case, the shark is the predator while the albatross is the prey.
300
What are adaptions?
It is the special characteristics that allow organisms to live successfully in their ecosystem.
400
Why is there less energy at the highest level of the pyramid?
Only 10% of energy travels to the next level of the pyramid since most of the energy at the bottom is used for the organisms' own needs.
400
Why are there less tertiary consumers than producers?
Not all of the energy is passed down. Only 10 percent goes to the next consumer. Because of this, there is not as much energy left for tertiary consumers
400
What plays a significant role in ecology and the flow of energy?
Photosynthesis.
400
How does a predator's/prey's adaptations help them survive?
A predator's adaptations often help them catch their food and survive in the area, while a prey's adaptations help them stay alive and not get eaten by the predator.
400
Why can't two species occupy the same niche?
Because they have to fight over the same resource and eventually, one of them will win the resource.
500
Why are there more producers than consumers?
Since the energy starts at the bottom of the pyramid, producers have more energy to use for their needs. Only some energy will be able to move to the next level in the pyramid now that the producers have used most of it, and this limits the amount of consumers an ecosystem can support.
500
Why is it important that none of the parts in a food chain die out?
If one part of a food chain is not there, a chain reaction will occur. All animals higher up on the food chain might starve.
500
How do producers get energy besides the sun and water?
they get extra energy from decomposers that give energy to them by breaking down nutrients into the soil to help them live.
500
How does predation affect a population's size?
When there are many predators out for food, there'll be a decrease in prey population, which results in less food for the predators. This then decreases the predator's population. Generally, predators' and prey's population size rise and fall in repeated circles.
500
What are three types of adaptations?
Camouflage, defensive chemicals, and warning coloration.
