Answer:

Soil particles vary greatly in size, and soil scientists classify soil particles into sand, silt, and clay. Texture indicates the relative content of particles of various sizes, such as sand, silt and clay in the soil. Texture influences the ease with which soil can be worked, the amount of water and air it holds, and the rate at which water can enter and move through soil. Soil provides plants with foothold for their roots and holds the necessary nutrients for plants to grow; it filters the rainwater and regulates the discharge of excess rainwater, preventing flooding; it is capable of storing large amounts of organic carbon; it buffers against pollutants, thus protecting groundwater.

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.

BlackZzzverrR [31]

Explanation:

In the given question, the graph and table have not been provided either they are found anywhere, therefore, the question has been answered on previous knowledge.

The species of Earth can adapt to their environment but adaptation in organisms can take a long time that is thousands to Lakh of years. But the rise in temperature is observed constantly past 200 years.

The species living in the tropics, equator and Poles are already adjusted for their thermal limit. If the average temperature of the planet will increase by 1°C then the number of individuals in the population will decrease. As the number of individuals will decrease, the number of population of species will decrease.

Due to this declination, the number of species can become extinct and therefore the process of increase in temperature and number of species that become extinct can be co-related.
