Biodiversity is essential to an ecosystem's resistance against viruses and famine. In history, there has been many cases in which a lack of biodiversity has allowed a virus or disease to endemically wipe out an entire species of plant. This will subsequently affect all consumers of each trophic level. Ex: A disease that attacks the DNA of only one certain species of plant would cause decreases in the population of the organisms that rely on eating that plant, the organisms that rely on eating those organisms, and so on. This is caused by a decrease in food source, thus not being able to sustain the ecosystem's demand, thus naturally killing off any organisms that would not be able to find a sufficient food source.
Answer:
They are sections of DNA that produce the proteins that control an organism's characteristics.
Explanation:
- <em><u>Genes are units of heredity found in a certain place on a chromosome and that codes for a certain product.</u></em>
- A trait of an organism is a characteristic that an organism can pass on to its offspring through its genes
.
- Genes are sections of DNA that contains information which controls a trait. Therefore, a trait depends on genes. Therefore; genes are the sections or segments of DNA that code for a specific trait in organisms.
