Each trophic level has a smaller amount of organisms or biomass than the one below it because it is only absorbing 10% of the energy from the lower level, so there is not enough energy to sustain larger numbers.
- A trophic level refers to a level in the food chain consisting of the same or biologically similar organisms. Examples of trophic levels include producer, consumer, and decomposer.
- Organisms in the lower trophic level serve as food for organisms in the next trophic level of the food chain.
- Only about 10% of the energy derivable from one trophic level gets to the next trophic level, the remaining is lost as heat during metabolic processes.
- Hence, the number of organisms progressively decreases as we climb higher in the food chain. The limit to the amount of energy transferred as we move higher means that the number of individuals that can be sustained will also be limited.
<em>The correct option would, therefore, be D.</em>

Sampling is the process of s<u>electing individuals or smaller groups from a larger population</u> to act as <u>representatives of that population.</u> This is used to make statistical assumptions and infer the traits of the population as a whole.
Sampling techniques can be divided into many categories and subcategories. There are four main forms of sampling, which include:
- Simple random sampling.
- Systematic sampling
- Stratified sampling
- Cluster sampling
Each of these can then be divided further.
Sampling techniques can sometimes be random, <u>intended to avoid biased choices that benefit the achievement of the desired result</u> and therefore render the conclusion inaccurate. This is the biggest weakness in sampling methods. Errors in sampling can lead to <u>false assumptions and misleading data. </u>

Answer:
Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.
Explanation:
Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body. Waste products of digestion pass through the large intestine and out of the body as a solid matter called stool.
