(a) Aquatic ecosystems are rich in diversity. The life inside water is largely influenced by various abiotic factors. The abiotic factors are the chemical and physical components of an environment that affect the organisms living there. The primary abiotic factors that affect the life underwater are temperature, light and availability of oxygen.
(b) Oxygen available to the aquatic organisms is a detrimental factor. If less oxygen is available underwater aquatic animals will not be able to respire and die.
Light is also an important abiotic factor for underwater organisms especially for the aquatic plants. the aquatic plants underwater will not be able to make their food by photosynthesis if proper light is not available.
Temperature also plays an important role. Too low or too high temperature affects the metabolic activities of the organisms.
Depth of water body affects the availability of light and oxygen to the aquatic organisms. Shallow water bodies have light available to more aquatic organisms.
The correct answer is C.
Amino acids consist of two different parts, the nitrogen-containing portion (NH2 group, dor the amino acid) and the carbon skeleton, containing the COOH, the acidic part. Two amino acids form bonds between their amino and acidic parts and form peptides that build up to proteins.
Presumably whatever their nutrition and health requires, for instance, if a tree frog requires fruit flies to maintain a healthy and balanced diet, then the conservation center probably feeds their tree frogs fruit flies.
<h3><u>Answer;</u></h3>

<h3><u>Explanation</u>;</h3>
- Dichotomous keys are biological keys which are sets of statements that act as clues leading to the identification of an organism.
- Dichotomous key is a biological tool for identification of unknown organisms.
- A single characteristic is considered at a time. Two contrasting statements are put forward to describe the characteristics in such a way as to separate the organisms, which continues until the organisms have been identified.
