What is true of matter in ecosystems?
Sidana [21]
D.Elements continuously cycle between the physical environment and living organisms.

Ecosystem is encompassing all the life on earth in the physical environment that supports it. An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.  <span> </span>

Why do plants produce less oxygen during the night
Naily [24]

Answer:

<em>Plants give out carbon dioxide not only at night but during the day too. It happens because of the process of respiration in which plants take in oxygen and give out carbon dioxide. As soon as the sun rises another process called photosynthesis starts, in which carbon dioxide is taken in and oxygen is given out</em>

A plant may open and close its stomata to prevent excess water loss and maintain _____. adaptability homeostasis negative feedba
Harman [31]

The correct answer is the homeostasis.

A plant may close and open its stomata to prevent excess water loss and maintain homeostasis.

Homeostasis is termed as the tendency of organisms to maintain and automatic regulation of their internal environment to be in a stable condition.

We say that the plant is in stable condition when the fluid balance and body temperature are being kept in to a pre-set limits which include calcium ions, potassium, sodium and PH of extracellular fluid.

The natural resistance which changes the optimal condition brings about homeostasis.

Plastics clearly constitute an important component of the range of materials used in modern society. Almost all aspects of daily life involve plastics or rubber in some form or the other. ... Owing to their light weight, plastics reduce transportation costs and, therefore, atmospheric carbon dioxide emissions./Plastic is durable and provides protection from contaminants and the elements.
