Summary Introduction
To review:
The cause for an algal bloom and its consequences.
Introduction:
When the algal growth increases and get accumulated in a freshwater or marine ecosystem is known as algal bloom, it can adversely affect the lifecycle of other aquatic life. Eutrophication is a natural process that occurs gradually over time but can be accelerated by the anthropogenic activities. It leads to an algal bloom.

- Refer to the description and table below to answer the three question that follow: Dissolved oxygen levels from 3 bottles of algae were recorded. The DO level of bottle #1 was recorded immediately after the algae was collected, the DO level of bottle #2 was recorded after sitting for 20 hours wrapped in tin-foil, and the DO level of bottle #3 was recorded after sitting for 20 hours under a lamp. A heat sink was placed over all of the bottles to ensure that temperature did not have an effect on the results. The following data was collected: Bottle Number D.O. Level 8 #1 #2 1 #3 6 4.

While some researchers are of the view that the association is a type of parasitism, most researchers believe that the symbiotic association between algae and fungi in lichen is A.) ammensalism B.) mutualism C.) neutralism D.) commensalism 2.) Which of the following statements about intraspecific competition is not correct? A.)Intraspecific competition exists between members of the same species. B.)Species members compete for food. C.)

Part of the digestive tract of ruminants contains a microbial community that can break down cellulose. These microbes gain energy from the plant material, and byproducts of their metabolism provide the host with a source of Carbon and energy. What type of symbiosis does this relationship describe?arrow_forwardPunctate, errose, lobate, dry, convex, swarming, yellow, and circular are all terms that describe: anabolism cellular morphology colonial morphology catabolismarrow_forward
