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

Answer 1
Answer:

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.

When you heat up an object, the particles in the object move which way?

Answers

When you heat up an object, the particles in the object move away from the heat source. The heat energy form the source transfers to the particles which causes them to be excited to move and go in any direction away from the source. It increases the kinetic energy of the particles.
