Explanation:
Bad water quality can impact the ecosystem by pollution. Pollution can lower the oxygen levels. It can also kill plant and animal life in an ecosystem. The living things in the water could die and it could also affect the water we drink. If the water is not clean we could also get sick.
Answer:
A carbon dioxide and water
<em>water is important because it gives space to the substances to get in it also it makes the substances wet and dissolve the gases in it ,to transport them from one place to another... </em>
Answer;
-Evolution by natural selection
-The theory of evolution by natural selection states that organisms that are better suited for their environment will survive and reproduce, while those that are poorly suited for their environment will die off.
Explanation;
-The theory of evolution encompasses the well established scientific view that organic life on our planet has changed over long periods of time and continues to change by a process known as natural selection.
-Natural selection is the phenomenon that some traits confer a reproductive advantage (fitness), resulting in (a statistical expectation of) that trait increasing in the population over time (evolution).
Answer:
A. Nuclear reactors increase thermal pollution
Explanation:
From the analogy provided in this context, we can vividly see that the author is suggesting that the use of nuclear energy causes thermal pollution.
- Nuclear energy is an alternate energy source as identified in the text.
- Since a huge amount of heat energy is generated and they are not all used up, they are released into the ecosystem.
- The earth is usually depicted as heat reservoir.
- Increased release of heat to the environment will cause thermal pollution.
- This increases the ambient temperature of water and degrades it.
