Explain how bacteria don’t over run the earth

Biology
1 answer:
Ede4ka [16]3 years ago
6 0

Competition and lack of nutrition are probably the main reasons – just like with any organisms, and to a much lesser extent inhospitable environments And like myth said, other species are capable of defending themselves.  For example, some eukaryotic unicellular organisms eat bacteria, and bacteria compete for nutrients against one another, as well as against other microorganisms living in the same ecological . For example, many molds secrete substances that kill or inhibit bacterial growth. Even  if there wasn’t any direct competition by other organisms, bacteria couldn’t "take over the world", if by that we mean that they’d cause the extinction of all other life forms and would be the sole survivors on this planet: there’d always be lots of habitats that are inhabitable for bacteria – mainly very dry (or cold) places, where vegetative bacteria survive only when living as symbionts or parasites on multicellular organisms that can survive there. So in other words, even if bacteria could rid the world of other living creatures, it would be against their best interests in many cases, and thus natural selection wouldn’t direct their evolution that way.

By leaving crop roots in the ground and stalks on the surface, no-till plowing helps prevent ____________________.
shusha [124]

Answer:

Soil erosion.

Explanation:

No-till plowing can be defined as a farming method or technique which typically involves planting crops (seedlings) without tilling the soil rather the farmer would only open a narrow or very shallow trench of sufficient depth and width to cover up the seedlings. Thus, the no-till plowing makes crop residues to be left on the soil and by extension preventing soil erosion through the absorption of water by the crop residues.

Hence, by leaving crop roots in the ground and stalks on the surface, no-till plowing helps prevent soil erosion.

Additionally, the water retention ability of no-till plowing is usually a boon to farmers because it slows down evaporation and serves as a good protection for drought-stricken environments.

How are photosynthesis and cellular respiration alike?
vampirchik [111]

The two main processes by which plant cells absorb, release, and use energy are photosynthesis and respiration. The process of photosynthesis is present in the chloroplasts of a pant cell. Photosynthesis uses the sun’s rays in the form of electromagnetic energy to convert it into chemical energy to be used for the plants. It needs proteins that are present in the plants to perform a series of necessary conversions. Moreover, the energy from the sun is the main catalyst to convert the carbohydrates in the plant into simpler sugars. And then a series of complex reaction takes place that their end product is oxygen. The oxygen produced is the cellular respiration.
