As the number of organisms increase so does their tropic levels. As one organism eats the other energy is being transferred to that organism. The larger the food chain the lesser the organism' s would be because they would lose energy while trying to hunt and catch their prey and other activities. The food chain usually ends at the tertiary consumer or the fourth link because if it goes on like that there would be less energy hence these organisms would most likely starve and gradually die.
The answer is an enzyme.
When cutting DNA, scientist uses enzymes called restriction enzymes. These enzymes are naturally produced in bacteria as a defense against phages. So, enzymes cut DNA of the phages and thus inactivate it. Also, these enzymes do not cat DNA randomly, but on specific sites. This characteristic of restriction enzymes is used for some molecular biology techniques. All species' DNA contains target sites of restriction enzymes, but most organisms do not have restriction enzymes. Therefore, restriction enzymes are suitable for different techniques.
Answer:
Explanation:
Natural selection is based on Darwin’s observation that individuals most likely to survive and reproduce are those with traits best suited to their current environment.
conduct research on the types of organisms that live in the ecosystem you choose -
Ecosystems, or biological communities, comprise both living organisms such as animals, plants, insects, and microorganisms and nonliving components such as rocks, soil, water, and sunshine.
- Producers are plants and algae that manufacture their own sustenance.
- Herbivores eat plants and are classified as main consumers.
- Secondary consumers are carnivores that devour herbivores at the third level.
- Tertiary consumers are predators that consume other carnivores.
