1. One biotic factor that affects consumers in an ocean ecosystem is2. A. number of autotrophs
3. B. temperature variation
4. C. salt content
5. D. pH of water

Answers

Any change that might affect a link of the trophic web, will inevitably cause a cascade effect in the whole web. In the exposed example, the number of autotrophs is the biotic factor affecting consumers in an ocean ecosystem.

---------------------------------------------------------------------------------------------------

In oceanicand terrestrial ecosystems, organisms build nets of varying levels of interaction known as the trophic webs.  

The trophic web is a relationship process between different organisms, through which occurs transference of energy. The ones placed at lower levels pass energy to the ones at the higher levels.

Organisms at eachlevel feed on the preceding one and become food for the next one.

As it is a web, all organisms are equilibrated until a change occurs. When the change affects any of the involved links, there can be a cascade effect on the web. A change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.

Also, when two or more species are competing for the same source of food, a change in any of the population sizes will affect the other ones.  

In the exposed example, we need to say which of the options are BIOTIC factors that affect consumers.

Among the options, there are temperature variations, salt content, and pH of water. All of them are significant factors that influence oceanic life. However, they are ABIOTIC factors.

The remaining option is the number of autotrophs. This option is a BIOTIC factor and is also the first link of many trophic chains.

Any change that might occur in this link -increasing or decreasing these populations-, will affect the whole system, beginning with their consumers.

Describe how Mendel showed that the green-seed trait did not disappear but was only masked.

Answers

Mendel had determined that the allele for green seeds had not vanished because after the second generation of yellow seeds, green seeds started appearing again. He logically concluded that the yellow allele was a dominant trait and the green allele was a nondominant trait.

Phosphorescence is a phenomenon associated with which algal division

Answers

Phosphorescenceis related to fluorescence in that the phosphorescent does not re-emit theradiation it absorbs. It is a process in which the absorbed energy of asubstance is released relatively slowly inn the form of light. One example ofthis is the glow in the dark stick. The stick will glow even brighter if it isexposed in a light material. Another example that is a phosphorescentassociated in algal division are the Pyrocystis fusiformis. They are dinoflagellatesand can glow brighter at lighter conditions

Answer:

Dinoflagellates

Wind flows from ____ pressure to _____ pressure

Answers

Answer
Wind flows from high pressure to low pressure​
Explanation:
Gases move from high-pressure areas to low-pressure areas. And the bigger the difference between the pressures, the faster the air will move from the high to the low pressure. That rush of air is the wind we experience.
