All living and nonliving things in an environment and the many ways they interact.
What is an ecosystem?
100
First, put the bread in the bag. Next, put a little water in the bag. Then, close the bag tightly. Finally, check the bag every day to see if there is any mold growing to decompose the bread.
Explain the order or sequence of the steps we took in our bread experiment.
100
The niche or job of the desert roadrunner is to chase food and escape predators. The habitat of the desert roadrunner is the desert.
What is the difference between the niche and the habitat of a desert roadrunner?
100
a producer
Grass is an example of a ___________.
200
All the members of one species that live within an area of an ecosystem.
What is a population?
200
Because it has parts that work together for a purpose.
Explain why a desert is a system.
200
sunlight-->algae-->freshwater snail-->blue heron
Put the following words in the correct order for a food chain: blue heron (bird), algae, sunlight, and freshwater snail. Be sure to tell where the arrows go to show the flow of energy.
200
A food web is made up of many food chains where energy flows in many directions. A food chain only shows energy moving in one direction.
Explain what a food web is and how it differs from a food chain.
200
Wings
_______are an adaptation needed for an animal that eats nectar from plants (think about hummingbirds, bees and butterflies).
300
All the organisms in a desert ecosystem.
What is a community?
300
an animal that eats plants and animals.
What is an omnivore?
300
To put the minerals and nutrients back into the soil, air, and water so that they can be used by living plants that will then be eaten by animals who will be eaten by other animals until they die and the whole process starts over.
How is a decomposer necessary to the continuing cycle of life in an ecosystem (explain the purpose and how it starts a new cycle).
300
It will probably decrease.
If the amount of food decreases in a community, will the population of birds be more likely to increase or decrease?
300
consumer
Zooplankton in a food web is a _____because it must take in food.
400
The specific role an organism has in its habitat.
What is a niche?
400
Nutrients and minerals
What are two things that are necessary to animals and travel through a food chain?
400
The sun shines on the grass, which is a producer. The cow eats the grass to get energy, then the coyotes eat the cow to get energy, and the farmer shoots the coyote for killing his cow (or the coyote dies of old age), and the vulture comes and eats the meat of the dead coyote. Then bacteria continues to decay the remains of the coyote, turning it into nutrients for the soil.
If you have a cow, sunlight, a coyote, grass, bacteria, and a vulture, how would you explain (or draw) the food chain to show how the cycle works?
400
Change
If a population of field mice die due to disease, will the food web stop, die, or change?
400
Sunlight
__________is the main energy source for life on Earth.
500
Organisms that digest the waste and remains of dead plants and animals.
What are decomposers?
500
Habitat
What do you call the hole where a prairie dog lives?
500
1. The plant uses nutrients from the soil. 2. The plant dies and begins to decay. 3. Earthworms eat decaying matter. 4. Nutrients are returned to the soil.
Put the following into the correct order: *Earthworms eat decaying matter. *The plant uses nutrients from the soil. *Nutrients are returned to the soil. *The plant dies and begins to decay.
500
Herbivores eat plants (herbs), Omnivores eat both plants and animals, Carnivores eat meat, and Scavengers eat dead or decaying meat.
How are herbivores, omnivores, carnivores, and scavengers different from one another?
500
minerals
Decaying animals put _______ back into the soil to help create the next generation of organisms.
