The work of Rachel Carson and the other ecologists has revealed the terrible consequences of the overuse of DDT. These ecologists worked at the ecosystem level of environmental interaction because they studied the depth of relationships between organisms and their environment.
An ecologist studies environmental problems and determines what causes them and how to improve the situations. In research, they gather data and analyze that for importance. Although, DDT (Dichloro Diphenyl Trichloroethane) was developed or invented as the first of the modern synthetic insecticides in 1940.
Hence, Rachel Carson and other ecologists found that overuse of DDT causes harm to the human liver and reproduction. As a result, humans face symptoms like vomiting, tremors, or shakiness. These problems were affecting the ecology and causing environmental disbalance. So those ecologists were working on the ecosystem level to solve the problem.

Answer:
Yes.
Explanation:
Bacteria are the simplest of creatures that are considered alive. Bacteria are everywhere. They are in the bread you eat, the soil that plants grow in, and even inside of you. They are very simple cells that fall under the heading prokaryotic. You don't usually get infected by dead bacteria, because They get recycled. Unlike larger organisms, when single-celled organisms die, they usually undergo a process called lysis, in which the cell membrane disintegrates.
