Vocabulary
100
What do living things get from their environments?
They get food, water, oxygen and space from their environments.
100
List some different types of ecosytems.
Deserts, grasslands, forests, oceans, freshwater...
100
What is any trait that helps an animal survive? what are the two types of it? what is the difference between them?
It is an adaptation. There are behavioral and physical adaptations. Behavioral: learning how to do something or knowing how to Physical: What you inherit or look like
100
How does nature cause changes to an ecosystem?
with fires or floods.
100
What is an environment?
It is the nonliving things and living things that surround a living thing.
200
What are some nonliving things that can be found in an environment?
water, rocks, air, soil...
200
Compare and contrast how plants and animals have adapted to living in a desert ecosystem with little water.
Plants: Have thick stems that store water Same: Plants and animals can survive on very little rain. Animals: find shay places to sleep; drink little water; get water by eating.
200
What are the two types of behavioral adaptations? Provide examples.
Learned and instincts. Learned: Using tools, reading, hunting Instincts: Sleeping, eating, migrating, hibernating
200
What happens to an organism when an ecosystem changes?
Populations grow or shrink, depending on resources. Animals may die or move into or out of the area.
200
What is an ecosystem?
It is made up of all living and nonliving things that interact in an environment.
300
What are the parts of an ecosystem?
population, community and habitat
300
How are grassland ecosystems different from desert ecosytems?
Grasslands get more water; they are always hot in the summer and dry in the winter. Deserts can be hot or cold.
300
What kind of adaptations are plants capable of? Provide an example.
They can only have physical adaptations. Examples; Different roots, leaves, stems...
300
How can people help ecosystems instead of harming them?
People can plant new trees; provide habitats for animals; preserve forests...
300
What is a population? Provide an example of one.
It is a group of the same kind of living organism in the same place. Example: human population, dolphing population, tree population...
400
What is the place where a population in an ecosystem lives called? what does it provide for a living thing?
It is a habitat. It provides everything a living thing needs to survive.
400
What kind of forest ecosystem grows where it is hot and wet? List a nonliving thing and living thing that could be in that ecosystem.
A rain forest. Nonliving thing: water, soil, rocks... Living thing: trees, monkeys, jaguars...
400
What is hibernations? List an animal that hibernates. What two things happen to a hibernating animal's body?
Hibernation is a sleeplike sate animals go into for the winter. Examples: bears, squirrels, bats... Body temperature drops; heart rate slows down.
400
What are the three important resources in an ecosystem?
Water, soil, plants/trees
400
What is all of the populations that live in an ecosystem at the same time called?
It is a community.
500
What is the difference between an ecosytem and an environment? Give an example.
An environment is the living and nonliving things that SURROUND A LIVING THING. An ecosystem involves interactions of the living and nonliving things. Examples: A fish's environment is a pond. An ecosytem for many animals as a pond.
500
What is the largest ecosystem in the world? How much of Earth does it cover? List a nonliving and living thing that could be in that ecosystem.
The saltwater ecosystem. It covers 75% of Earth. Nonliving: rocks, sand, salt, water... Living: dolphins, wahles, seaweed...
500
What are the three reasons animals migrate?
to get away from the cold, to find food, and to raise their young.
500
How do ecosystems change?
Nature causes change by means of fires, floods, and the activities of living things. People cause changes when they cut down trees, pollute water and air, and build homes and schools.
500
What is the adaptation called that allows animals to look like their environment and not be easily seen?
It is camouflage.
