Since shrimp pray on photosynthetic organisms, they are dependant on their prey's location.
The photosynthetic organisms need sunlight in order to produce energy, so they then to live in shallow waters, because the sunlight penetrates only a small upper layer of the water's surface.
So, shrimp live in shallow waters because their pray can only live there.
Answer:
C
Explanation:
Mutualism is a relationship between two parties where <em>both parties </em>are benefited.
This means the answer would be C- "Ants feed on aphid wastes and protect the aphids from predators."
The <em>ants</em> benefit from a feeding source.
The <em>aphids</em> benefit from predator defense.
<u>In answer C, both parties are benefited, so this is mutualism!</u>
I think the correct answer would be the third option. Organisms that help break down dead organic material so it can be recycled into a usable form for other organisms are called decomposers and this would include some of the bacteria. Also, there is a number of bacteria that are capable of breaking down some of the harmful products like in recent studies there are bacteria that could dechlorinate the toxic PCB substance. Some bacteria, as well, lives in the human intestines which aids in the breaking down of the food into useful molecules. The third option is partially true since there are some bacteria like the cyanobacteria which produces oxygen but it does not contribute largely to the oxygen present in the atmosphere.
Mosquitos are an example of organisms with r-reproduction strategy. This means that they tend to overproduce, have many offspring , but do not provide care for them. This happens because those organisms live in unstable, unpredictable environments, so rapid reproducing is very important. R strategy helps them produce a huge number of offspring, because at least some of them will survive to reproduce.
Elephants are an example of organisms with k-reproduction strategy, meaning that they have few offspring at a time, take care of them and have a long live span. These organisms occupy more stable environments, usually are stronger, better protected and more energy efficient. Their reproductive strategy is to grow slowly and to produce offspring with high probability of survival.
