List the characteristics of life that plants and animals in a food web share

Answers

Answer:They are movement, nutrition, respiration, sensitivity, reproduction, excretion,and growth.

Explanation:

Matter are anything that is made up of atoms. The quantity of matter can be observed only on the basis of mass and volume calculation. Thus, movement, nutrition, respiration, sensitivity, reproduction, excretion and growth are  the characteristics of life that plants and animals in a food web share.

What is matter?

Matter is a substance that has some mass and can occupy some volume. The matter is mainly used in science. Matter can be solid, liquid or gas.

So as we saw that matter has some mass so mass can be measured in gram only. Mass can also be represented as number of molecules. We also saw that matter occupy some volume and that volume is measured only in liter. Movement, nutrition, respiration, sensitivity, reproduction, excretion and growth are  the characteristics of life that plants and animals in a food web share.

Thus, movement, nutrition, respiration, sensitivity, reproduction, excretion and growth are  the characteristics of life that plants and animals in a food web share.

What is the affect of increasing the temperature of the water?
What happens when you add pollution to the water?
Can coral survive bleaching?
What is coral?

Answers

Answer:

Explanation:

Increasing temp in water makes it start to boil and evaporate into the atmosphere, in terms of climate change it makes it hard for many organisms to survive because they have to adapt quickly to the waters rapidly rising temperature. When you add pollution to water the water would become contaminated and not be able to support life or be fit for human consumption.

Coral cannot survive bleaching because it harms the coral to the point of its destruction.

Coral is an animal that can grow into big reefs that create large ecosystems for many organisms. They are in the ocean. The biggest coral reef is the great barrier reef in Australia.

Answer: High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. ... When you're not in one of the bulges, you experience a low tide.

Many people now blame the companies that produce junk food for our nations weight problems. Junk food companies are scrambling to save their reputations. One way to reach this goal is to sponsor community events and activities, such as sports games. Sponsoring an event means the company helps pay for the event. It also means the company gets to put its logo on all items connected with the event. By putting their logos on sports uniforms and other items, the companies can increase their presence in peoples minds. In other words, sponsoring such events allows companies to advertise their products. Companies can also claim that they are helping to keep kids healthy by supporting sports and other healthy activities. For example, in Australia, a soft drink company has sponsored under-13 rugby, junior soccer, and junior basketball school tournaments. All this sponsoring goes against the companys policy of not advertising to kids.
