Charles Darwin, is the scientist is the father of evolution
Answer:
Explanation:
In a lake, oxygenic phototrophs produce new organic material as well as O₂. If primary production rates are very high, the resultant excessive organic matter production can lead to bottom-water O₂ depletion from respiration and the development of anoxic conditions. This in turn stimulates anaerobic metabolisms, including anaerobic respirations and fermentations.
Organic matter that is not consumed in surface layers sinks to the depths and is decomposed by anaerobes.
Pond water contains a variety of plant and animal life. While some are visible to the plain eye, others require a microscope to observe them. For example, there's bacteria, protozoa, hydras, algae, and arthropods. You will have the opportunity to see a number of microorganisms from both the plant and animal kingdom.
the flowers are generally so beautiful and attractive to attract birds and insects for helping the plant to reproduce. when the bird or insect lands on some other flower, some of the pollen spreads and pollination occurs.
