What is the purpose of decomposers breaking down the dead remains? (hint: it does what for the soil?)
What is give back nutrients to the soil so plants can grow.
100
True of false, species of the same community share the same niche.
What is false, no two species have the same niche in a community.
100
Explain how a pond is a small ecosystem.
What is the pond contains plants or algae that feed underwater organisms or other animals. But it also may be apart of a larger ecosystem.
100
What would happen if the suns energy was blocked?
What is everything would die.
100
What is a predator and what is prey?
What is a predator is a organisms that hunts and feeds on other organisms. The animal being hunted is the prey.
200
What is the difference between abiotic and biotic factors? Give an example of each.
What is abiotic anything that has never lived example, a rock. Biotic anything that is living or was once living. Example, plants or animals.
200
A animals niche depends on its _________.
What is adaptations.
200
What is the main cause of changing ecosystems? Explain.
What is human interaction. We may cut down trees, build, etc.
200
What are producers, consumers, and decomposers? Where do each of them get their energy?
What is producers are plants that produce their own food using the suns energy. Consumers eat producers or other consumers for energy. Decomposers get energy from the dead remains of producers and consumers.
200
What is a host?
What is the organisms that parasites live and feed off of.
300
What is decomposing? Give an example of a decomposer.
What is the breaking down of dead plants or animals to give nutrients back to the soil. Fungi is a type of decomposer.
300
Describe each. A community, a population, a species.
What is a community is made of organisms living together in an ecosystem. A population is a group of the same species in a community. A species is an organism.
300
How can ecosystems change naturally?
What is new plants and animals or natural disasters may destroy or create an ecosystem.
300
What are herbivores, carnivores, and omnivores? Give an example of each.
What is herbivores eat JUST plants - deer. Carnivores - eat JUST meat - wolves. Omnivores eat plants AND meat - humans.
300
Describe a predator prey relationship.
What is if the predator increases, the prey decreases. If the prey decreases, the predator decreases. If the predator decreases, the prey will increase. If the prey increases, the predator will increase. This continues in a circle.

What is an ecosystem?
What is when organisms interact with each other and their PHYSICAL environment.
400
Explain the difference between a niche and an adaptation. Give an example of each.
What is an adaptation is a physical characteristic that allows an organism to survive in its environment. Example, a dogs fur may become heavier or thicker in the winter. A niche is the role a species plays in its community. An example is a bee. A bee may be in charge of finding food, building a nest, or they may be the queen bee

How can a large ecosystem contain smaller ones?
What is a large field may have a snake hole or a rabbit whole. A rain forest may have broken trees that organisms live in or lakes and rivers. etc.
400
True or false, decomposers are not a type of consumer.
What is false, they consume dead consumers and producers.
400
What is symbiosis?
What is when two organisms have a relationship with one another where one may benefit and hurt the other, both may benefit, or one may benefit without affecting the other organism.
500
Explain the boundaries of an ecosystem.
What is ecosystems have no boundaries because they can overlap. A rain forest may be a large ecosystem with many organisms but within the rain forest, their may be a pond ecosystem, or a tree with an ecosystem. etc.
500
How are communities, populations, and species related? Give an example, or draw one.
What is a species is one organism but if you have two or more of the same species, they make up a population. If you have more than one type of species, you have two populations. Two or more populations make up a community.
500
Why might scientists find out what the dominant species in an ecosystem is?
What is they may need to know this because most of the other organisms in that ecosystem rely on the dominant species. This does not necessarily mean the organisms that eats the other organisms.
500
What would happen without decomposers?
What is nothing would be broken down. Therefore no nutrients would be given back to the soil. If the soil had no nutrients, no producers would grow. Without producers, consumers would die.
500
Name and describe the three types of symbiosis. Give an example of each.
What is Parasitism: one organisms feeds off of the other organism harming that organism. A flea on a dog. Commensalism: one organisms uses another organism without positively or negatively affecting that organism. A crab spider on a flower. It blends in with the flower so when insects land on the flower, it can eat them. Mutualism: when both organisms benefit. A barn owl and a farmer. The owl lives in the farm killing rodents that kill the farmers crops.
