Answer: Option B) Trophic level

Explanation:

Trophic level refers to a feeding level, representing the number of links by which food energy is transferred from producers

to final consumers.

For example

Grass ------> Antelope ---------> Lion

This food chain begins with grass as producer, that is fed on by antelope which in turn is fed on by a carnivore, lion. Thus, there are three trophic levels by which energy is transferred in a step-by-step basis from grass to lion.

Thus, trophic level is the answer

What is the structure of mitochondrion, cell wall, cell membrane, and the nucleus
Romashka-Z-Leto [24]

Answer:

The mitochondria are called the powerhouses of the cell, where ATP is produced. It is composed of an inner membrane called cristae, and an outer membrane that covers the organelle.

The cell wall is a rigid structure made from(in the case of plant cells rather than bacteria or fungi) cellulose and other rigid fibers.

The cell membrane is a fluid, thinner structure made up of a double layer of phospholipids which are comprised of the hydrophilic heads facing outwards and hydrophobic tails facing toward each other in the layer.

The nucleus  has protons, and neutrons that are contained within it, and electrons around it.

Human caused reductions of biodiversity, include pollution, invasive species, and overexploitation.
Andrew [12]

Answer:

True

Explanation:

Development, together with globalization, drove severe changes at a global level. The natural and original environments suffered from these effects and still are.

Human beings have constantly been altering the natural ecosystems and causing irreparable damages to nature. For many decades, development involved society and technology advance over new areas unpopulated by humans.

<u>Some</u> of the principal human activities responsible for biodiversity loss are

  • the uncontrolled use of unrenewable resources,
  • overexploitation of renewable resources;
  • land destruction for the mining industry, farming and cattle industry, buildings, and other infrastructures;
  • the unplanned advance of cities, and opening of new roads to connect those cities.  

All of them involving

  • deforestation and fragmentation of natural landscapes;
  • water, air, and soil pollution,
  • species loss, and reduction of biodiversity.

With globalization, transport around the world became normal. And when traveling around the world, new species are intentionally or unintentionally transported too. When these species, of animal or vegetable origin, get established in a new area, they overgrow to the point of turning invasive.

Invasive species are uncontrollable and cause severe damage in native endemic species by competing for resources. The whole ecosystem structure changes.

But there are some background glitches in the system that are the principal responsible for all the mentioned activities. Some important aspects are lacking

  • The respect for nature,
  • People´s education at different levels to care and protect wildlife,
  • Interest in keeping ancestral knowledge,
  • Planning and previous environmental impact studies,
  • Policies to control human activities,
  • Caring involved government.

If, as a society, we lack these aspects, the possibilities of changing our impact on nature are far away.
