explain how the energy producing processes occurring in the cells of organisms drives the cycling of matter within an ecosystem

Answers

Answer:

The flow of energy and cycling of matter can be traced. The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur. In this reaction, carbon dioxide and water combine to form carbon based organic molecules and release oxygen

The surface of rivers freeze when the temperatures falls below freezing. However, the water underneath this layer of ice continues to flow. This phenomenon allows fishermen to fish through holes drilled in the ice the entire winter. Which property of water is the reason the river doesn't freeze completely?

Answers

Answer: Water retains its temperature for long.

Explanation:

The ice floats on the water of river as it is less denser then the liquid water. This causes ice to float on water. It protects the water at the bottom from freezing. The decrease in the temperature level can cause the death of the marine life by catching organisms in the ice. The floating of the ice insulates the water present beneath. So, the fish and other aquatic animals can survive and the fishermen can catch the fishes alive.

1. Because the increase of temperatures.

2. Why they effect humans - Melting glaciers add to rising sea levels, which in turn increases coastal erosion and elevates storm surge as warming air and ocean temperatures create more frequent and intense coastal storms like hurricanes and typhoons.

2. Why they effect the ecosystems - Continual melt from glaciers contributes water to the ecosystem throughout dry months, creating perennial stream habitat and a water source for plants and animals. The cold runoff from glaciers also affects downstream water temperatures.

carbon has 4 electrons in the outer shell .how does carbon attain stable electrons configuration!if ur answer it points + i wil mark as brainlist so dont miss it..​

Answers

Because all atoms need 8 electrons in their outer (valence) shell, carbon, having four valence electrons, achieves stability by bonding with 4 other atoms. When doing this, carbon “gains” four more electrons that bring its total valence electrons count up to eight.

For example:

In CH4, carbon bonds with 4 hydrogens and the bonds between the carbon and each hydrogen “add” 4 electrons to carbons outer shell.

what is carrying capacity? what type of population growth does it affect?

Answers

Carrying capacity is referred to a population size of species in a particular habitat. In an ecosystem, the population of a species will increase till it reaches its carrying capacity. Then the population size remains relatively equal.

What are the types of carrying capacity?

Carrying capacity is the maximum limit till that the ecosystem can support the existence of the population.

There are four categories of carrying capacity, namely:

Physical.Ecological.Economic.Social.

A specific environment's carrying capacity is the maximum population size that it can support.

The carrying capacity modifies the growth rate by slowing it when resources become scarce and stopping growth once it is reached.

Thus, it can be concluded that the carrying capacity is the average population size of species in a particular habitat which slows and stops the growth rate on reaching it.

Answers

Answer: See explanation

Explanation:

Toxicology is a field in science that has to do with the effects of poisons, toxics and how they can be treated. Through toxicology, one can understand how harms are caused by chemicals and the health of the public can be protected.

Toxicologists study chemicals, drugs and other substances, and looks at how safe they're and their impact on living organisms. Toxicologists help in the development of methods that'll be used to know the harmful effects and the the dosages which causes it.

Furthermore, toxicology gives vital information and knowledge which the decision makers or regulatory agencies

in other biomedical fields can use in order to put programs in place that can be used to limit the exposures of humans to the substances.

In conclusion, less exposure to these substances is vital so that diseases can be prevented.

Toxicology is also used in the field of environmental health.

Toxicology will be important to other biomedical professions outside of forensics. Toxicology can be used in environmental health field which provides critical information and knowledge about the toxic substances that can be used by regulatory agencies to limit our exposures to toxic substances so we can say that toxicology plays an important role for other biomedical professions.
