(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.
Answer;
-Association areas
The association areas of the cerebral cortex are not involved in primary motor or sensory functions; rather, they are involved in learning, remembering, thinking, and speaking.
Explanation;
-The cerebral cortex is divided into sensory, motor and association areas. Sensory areas receive and interpret impulses from sensory receptors , motor areas control movement of muscles (initiate impulses to skeletal muscles). Association areas are involved with more complex functions such as learning, decision making and complex movements such as writing.
-Association cortex is the cerebral cortex outside the primary areas, The majority of the cortex is composed of this area. It is essential for mental functions that are more complex than detecting basic dimensions of sensory stimulation.
