Which TWO descriptions of plants explain how they contributed to the carbon cycle?
denpristay [2]

Plants stored carbon in their tissues to use as energy and plants took in carbon dioxide and released oxygen through photosynthesis. Thus, the correct option is A and D.

<h3>What is carbon cycle?</h3>

The carbon cycle is the ongoing process through which carbon atoms move back and forth between the atmosphere and the Earth. The amount of carbon in this system does not fluctuate because our planet and its atmosphere are a closed environment. The location of the carbon, whether it is on Earth or in the atmosphere, is continually changing.

Plants use photosynthesis to transport carbon from the atmosphere into the biosphere and move it up the food chain. They make sugar molecules by chemically combining carbon dioxide with oxygen and hydrogen from water using solar energy.

Two groups of tomatoes were grown under laboratory conditions, one with humus added to the soil (Group 1) and the other a contro
charle [14.2K]

Answer:

the humus contains the minerals necessary for chlorophyll synthesis

Explanation:

<em>The yellowness of leaves in plants can be attributed to inadequate chlorophyll in the plant</em>. The chlorophyll is responsible for the greenness appearance of the leaves of plants and when it is present in inadequate quantity, the leaves appear yellowish in color.

<u>Some of the minerals necessary for the formation of chlorophyll include magnesium, nitrogen, and iron</u>. It thus means that the humus supplied to the soil of group 1 plant has the necessary minerals to synthesize chlorophyll while the soil of group 2 plants is deficient in some or all the minerals required for chlorophyll synthesis.

The data table above includes the distance each planet is from the sun. Students in an Earth science class were asked to explain
Serga [27]

Student 4

Explanation:

  • The sun has less gravitational pull on Neptune because it is farther away. Gravity is the force by which a planet or other body draws objects towards its center.
  • Gravity keeps all the planets in its position and allows it to move in its orbit.
  • The force of gravity is inversely proportional to the distance between two objects.
  • So when the distance increases, the force weakens. Since Neptune approximately 4.8 billion kilometers away from the sun, its gravitational force is very less.
