Answer:
The statement that says "Energy enters a food chain as heat energy and leaves it as light energy" is false.
Explanation:
The energy that enters the food chains, first of all, is light energy from the sun. This energy is assimilated by plants to convert it into chemical energy, through photosynthesis.
When energy flows from producers, plants, to consumers and decomposers, a great amount of <u>energy is lost, in the form of </u><u>heat energy</u>, due to the metabolism of living beings. Additionally, the second law of thermodynamics states that when energy passes from one form to another it leads to disorder in the system, which would also explain the loss of energy.
The true statement is "Energy enters a food chain as <u>light energy</u> and leaves it as <u>heath energy"</u>.
Answer:
Deposition
Explanation:
Landslides occur under the effect of gravity. When a mass of rock or earth slides down from a mountain or from a cliff then this phenomenon is termed as Landslide.
Landslides are considered to be a rapid method of erosion. Wind, waves, running water, glaciers and gravity are the five agents of erosion out of which the gravity influences the process of Landslides.
Landslides occur suddenly and are dangerous example of the movement of earth materials under the influence of gravity. When weathered material falls away from a cliff, it slides down under the effect of gravity and finally after reaching the hill, the material gets deposited there. This is called Deposition by landslides.
Answer:
B. Meiosis I
Explanation:
In meiosis I, it starts with a diploid cell with a homologous chromosome pair. The crossing of genetic material between chromosome pairs also occurs in this stage. The alleles containing the same trait would get separated so a new combination of alleles can be produced.
Answer: Whether the culprit were too much sunlight or not enough, if photosynthesis stopped, plants would stop converting carbon dioxide -- an air pollutant -- to organic material.
