Write TRUE if the statement is correct. If the statement is false,
change the underlined word by writing the correct answer on your paper.
1. Biodiversity is a compound word derived from ‘biological diversity’. It is a
term used to describe the variety of living things on earth.
2. A community is a group of living things within a certain area that are all of
the same species.
3. A population of one kind does not affect a population of another kind
within the community.
4. Ecosystem Diversity is considered as a complex level of diversity.
5. Scientists use a formula called the population index to describe the
amount of species diversity in a given area.
6. A community with very low index of diversity is more at risk of extinction if
environmental changes occur.
7. A community with very high index of diversity consisting of many species
has a better chance of including individuals that might be able to adapt to
changes in the environment.
8. An ecosystem is a community of organisms interacting with the physical
environment.
9. An ecosystem is composed only of biotic (living) components.
10. Limiting factors are usually expressed as a lack of a particular
resource which can be biotic or abiotic that affect an ecosystem and the
organisms in it.
11. An increase in biodiversity also increases the adaptability of the
ecosystem to changing environmental conditions; thus, increasing
the population density
12. High biodiversity decreases the survival of organisms in an
ecosystem.
13. Low biodiversity can lead to species extinction.
14. When the population of a species decreases rapidly, the species is
considered endangered.
15. A species is considered threatened when its population is very low.
16. Extinction occurs when the last members of that species die.
17. Ecological imbalance happens when there is a disturbance that
disrupts the balance of an ecosystem.
18. The trapping of heat by gases in the earth’s atmosphere is called
greenhouse effect.
19. Global warming is an increase in the earth’s temperature from the
rapid buildup of carbon dioxide and other gases in the atmosphere.
20. Greenhouse effect is a man-made process​
