Which factor has greatest importance in determining the characteristics of an aquatic ecosystem? a. day length b. water depth c. angle of sunlight d. average precipitation

The correct answer is option B, that is, water depth.  

An aquatic ecosystem refers to an ecosystem, which is found in water. There are various kinds of the aquatic ecosystem, that is, lakes, rivers, wetlands, ponds, deep oceans, and shallow seas.  

The chemical or physical components of the environment, which influences the species that are thriving in particular surroundings are known as the abiotic factors. In the case of aquatic ecosystems, the abiotic factors are the flow rate of water, the intensity of light, temperature, acidity, dissolved oxygen, salinity, and water depth.  

Of these water depth plays the most significant role in determining the characteristics of aquatic ecosystems. The intensity of sunlight and the availability of the dissolved oxygen to the species depends on the depth of water in an aquatic ecosystem.  

d. in sexual reproduction, offspring have more chromosomes than

either parent.

asexual reproduction results in offspring which are genetically the same as the parent organism (not counting a rare mutation). sexual reproduction produces a random mixture of the genetics derived from both parents
