Is a bear a carnivore or omnivore?
Omnivore
Organisms that make their own food.
Producers
Will 2 bird populations that eat the same type of insects compete or not compete for their food?
Compete
Organisms that get their energy by breaking down dead organisms and animal wastes.
Decomposers
Several food chains that overlap each other create what?
Food web
A monkey lives in a tree, eats bananas, and reproduces in the fall. These interactions describe the organisms what?
Niche.
What gas is released during respiration as a waste?
Carbon dioxide
Is a rabbit a consumer or producer?
Consumer
What is not used up, but rather recycles in both the nitrogen and carbon dioxide-oxygen cycles?
Matter
Do plants or animals perform photosynthesis?
Plants
In an ocean, population A eats fish only and population B eats algae only.
What would happen if we introduced population C that eats algae only?
Population B would decrease: more competition.
What do a bunch of populations make up?
A community.
A bear hunts and eats a fish. Name the predator and the prey.
Bear: predator
Fish: prey
Is a lion classified as a carnivore or herbivore?
Carnivore.
What does a habitat do for organisms?
It provides them with basic needs for survival. (food, water, shelter)
Create a food chain with the following terms:
fish, algae, orca, shark
Algae - Fish - Shark - Orca
What are 3 things that help make nitrogen gas into usable nitrogen?
Lightning, soil bacteria, dead organisms/waste decay.
Please explain the term biodiversity.
The number of different species that live in an ecosystem.
In the following energy pyramid, which organism gets the smallest amount of energy?
Grass - Rabbit - Snake - Eagle
Eagle
What will happen if a resource becomes limited in an ecosystem?
Populations could decrease, more competition for resources.
In order, list the parts of an ecosystem.
Organism - Population - Community - Ecosystem
Please explain how energy flows in the following pyramid:
Grass - Rabbit - Snake - Eagle
The grass captures sunlight's energy.
The grass is eaten by rabbit: energy transferred.
Rabbit is eaten by snake: energy transferred.
Snake is eaten by eagle: energy transferred.
If a location has a small amount of species, will it have enough resources to support them?
No.
True or false: nitrogen gas in the air is not usable.
True.
True or false: animals get nitrogen when they eat plants.
True.
