These are the different populations that interact with each other in the same area.
What is a community?
100
These are all of the members of one species that live within an area of an ecosystem.
What is a population?
100
This is all the living AND nonliving things in an environment and the many ways they interact.
What is an ecosystem?
100
The specific role or job an organism has in its habitat is this.
What is niche?
100
These organisms make their own food.
What are producers?
200
These digest the waste and remains of dead plants and animals.
What are decomposers?
200
These consumers eat only animals.
What are carnivores?
200
These consumers eat both plants and animals.
What are omnivores?
200
These consumers eat only plants.
What are herbivores?
200
This is where an animal lives (its "address").
What is habitat?
300
If a population of birds in a community decreases, this will happen to the food in the community. (Increase or decrease?)
What is the amount of food decreases?
300
This has parts that work together for a purpose. For example: a desert, bicycle, wetland, etc.
What is a system?
300
This adaptation would be useful for an animal whose niche is eating nectar from plants.
What are wings?
300
This is the main energy source for life on Earth.
What is sunlight?
300
True or False... A worm is a producer.
What is FALSE?
400
An system of overlapping food chains is called this.
What is a food web?
400
The passing of energy from one organism to another in ONE DIRECTION is called this.
What is food chain?
400
This will happen if a population of animals dies of disease.
What is the food web will change?
400
These things travel through a food chain from organism to organism.
What are minerals and nutrients?
400
This is the role of the freshwater snail in the swamp food chain.
What is the snail eats algae and is eaten by the blue herons?
500
This is how decaying organisms help create the next generation of organisms.
What is decaying organisms put minerals back into the soil?
500
The zooplankton in a food web is a producer. TRUE OR FALSE.
What is FALSE? (Zooplankton is a consumer... it eats algae)
500
This is how organisms are connected in an ecosystem.
What is all organisms are part of a food web and there is an endless cycle. Sun is the main source of life. Gives energy to the producers. Herbivores eat the producers. Omnivores eat the herbivores. Carnivores eat the herbivores and omnivores. When the organisms die, decomposers return the nutrients back into the ecosystem and the cycle begins again.
