In what ways do humans affect the different trophic levels in ecosystems on Earth?

Answers

Answer 1

Answer:

Our results contrast with research conducted in protected areas that suggested human effects in the food web are primarily predator-mediated. Instead, human influence on vegetation may strengthen bottom-up predominance and weaken top-down trophic cascades in ecosystems.

Explanation:

Answer 2

Humans affect the different trophic levels in ecosystems on Earth through destroying it via activities such as habitat destruction, pollution etc.

What is Ecosystem?

This refers to all the organisms and the physical environment with which they interact.

Humans have destroyed most of the trophic level through predator mediated activities but however have increased the producers through agricultural processes.

In which part of the Sun would the most helium be found? *

Answers

Answer:

yes D part have most helium

The most helium in the Sun is found in its core. The core in the given image is represented by letter D.

What is nuclear fusion?

Nuclear fusion is the reaction that occurs when two or more atomic nuclei combine to form one or more different atomic nuclei and subatomic particles (neutrons or protons).

Nuclear fusion reactions take place in the Sun's core, converting hydrogen into helium and releasing energy in the process.

As a result, the core of the Sun has the highest concentration of helium, accounting for an estimated 60% of the Sun's total mass.

The outer layers of the Sun have much lower helium concentrations and are mostly made up of hydrogen.

Thus, the correct labeling is D.

The white-tailed ptarmigan lives at high elevations on mountains that receive a lot of snow in the winter. During the summer, the ptarmigans’ feathers are mottled brown. The birds lose the brown feathers and grow a new set of white feathers during the winter. Scientists are concerned that rising global temperatures will affect the white-tailed ptarmigan. If global climate change leads to the elimination of snow in the habitat of white-tailed ptarmigans, which adaptation is most likely to occur over many generations?

Answers

Answer:

The birds will no longer molt brown feathers for white ones.

Explanation:

Over time the birds with white feathers will slowly die off (mostly dude to predators), and over time the birds will likely no longer have white feathers, and they will no longer molt from brown to white and white to brown. The feathers will likely stay brown year round.

Answer:As one example, think about a building's electrical system. Suppose a mouse chewed through an electrical wire to a furnace. Without electricity, the heating system would not work. If this happened in very cold weather, the plumbing system could be affected. Water pipes might freeze and burst. If a lot of water leaked into the building's walls, its support system would be damaged. Like a building's systems, your body's systems have

Explanation:

You know that your body is made of cells. When groups of cells do the same kind of work, they are called tissues. The word tissue comes from a Latin word meaning to "weave." Cells that make up tissues are sometimes "woven" together.

You have four main types of tissues: epithelial, nervous, muscle, and connective tissue. Epithelial tissue covers the outside of the body. It also lines organs and cavities. Nervous tissue sends electrical signals. Muscle tissue helps you move. Connective tissue joins bones and cushions organs.

When groups of tissues work together, they are called organs. Some

examples of organs are the heart, lungs, skin, and stomach. When organs work together, they are called systems. For example, your heart, lungs, blood, and blood vessels work together. They make up the circulatory system.

There are eleven systems in the human body: muscular system, respiratory system, digestive system, integumentary system (skin), skeletal system, circulatory (or cardiovascular) system, excretory (or urinary) system, reproductive system, nervous system, lymphatic system, and endocrine system. Each system has a special job.

All of your body systems have to work together to keep you healthy. Your bones and muscles work together to support and move your body. Your respiratory system takes in oxygen from the air. It also gets rid of carbon dioxide.

Think of your body as a building. A building has a plumbing system, a heating system, a cooling system, an electrical system, and a support system. If any system in a building breaks down, other systems can be affected.

Answer:

Explanation:

The makeup of both water and isopropanol is different from each other due to their polar nature. Water is a polar substance means that it makes poles i.e. positive or negative while on the other hand, isopropanol is non-polar substance so due to this reason water and isopropanol make different layers. If both are polar or nonpolar substances so they will able to mix with each other.
