Answer:

\boxed {\tt D. \ Microorganisms}

Explanation:

A biotic factor is a living thing in an ecosystem. For example: deer, rabbits, grass and trees are all biotic factors.

An abiotic factor is a nonliving thing in an ecosystem. Some examples include rocks, soil, and water.

Let's examine our answer choices.

Sunlight, nutrients, and precipitation are all nonliving, so they are abiotic factors. They can't be the correct choice.

That leaves: <u>microorganisms.</u> Microorganisms are very tiny organisms, like bacteria and amoebas. They are biotic factors, so the correct choice is D. microorganisms

Describe the major fields of study that contribute to environmental science
IRISSAK [1]

Answer:

Environmental Sciences is a multidisciplinary academic field that integrates biological, physical and information sciences for the study of the environment and solutions to environmental problems. These sciences include physics, ecology, zoology, biology, chemistry, mineralogy, oceanography, geology, soil sciences, atmosphere sciences and geography. The environmental sciences emerged from the fields of natural history and medicine. Today, they allow an integrated, quantitative and interdisciplinary approach to the study of environmental systems.

Related areas of study include environmental studies and environmental engineering. Environmental studies integrate social sciences to understand human relations, perceptions and policies regarding the environment. Environmental engineering focuses on design and technology designed to improve the quality of the environment. Environmental problems almost always include the interaction of physical, chemical and biological processes. Environmental scientists work on topics such as understanding ground processes, assessing alternative energy systems, controlling and mitigating pollution, managing natural resources and the effects of global warming, applying systemic analyzes to environmental problems.

Environmental sciences became an active field of scientific research in the 1960s and 1970s, due to the need for a multidisciplinary approach to analyzing complex environmental problems, the emergence of various environmental laws requiring specific research protocols, and increasing public awareness. the need for action to solve environmental problems.

Describe in detail: What is cancer?
lisabon 2012 [21]

Answer:

Cancer can develop anywhere in the body. It starts when cells grow out of control and crowd out normal cells. This makes it hard for your body to work the way it should.

For many people, cancer can be treated successfully. In fact, more people than ever before lead full lives after cancer treatment. The cells in our bodies all have certain jobs to do. Normal cells divide in an orderly way. They die when they are worn out or damaged, and new cells take their place. In cancer, the cells keep on growing and making new cells. They crowd out normal cells. This causes problems in the part of the body where the cancer started. They can also spread to other parts of the body.

How does the greenhouse effect influence the climate on earth? choose the best possible answer.
Arturiano [62]

The greenhouse effect influences climate by increasing the global temperature.

<h3>What is greenhouse effect?</h3>

The greenhouse effects are effects due to the presence of greenhouse gases in the atmosphere.

The greenhouse gases form a layer of gas in the atmosphere and prevent reflected solar radiation from escaping back into space. They, therefore, warm up the atmosphere by increasing the thermal energy.

As the concentration of the greenhouse gases in the atmosphere increases, so also is the amount of reflected solar radiation that is trapped in the atmosphere.

Therefore, an increase in greenhouse gas concentration increases the global temperature. Temperature influences other climatic factors such as precipitation.

Thus, the greenhouse effects influence climate by causing a rise in global temperature.
