Select all that apply. select all that apply. organism size increased by about 30% after the establishment of this reserve. the density of all the organisms in an area can be expected to increase after the establishment of a reserve. an increase in the number of predators in a community correlates with a decrease in the number of grazers (sea urchins in this case). kelp forest recovery in marine reserves is likely due to an increase in predators. because reserves have a higher diversity of species, individuals of each species are, on average, smaller. if lobster harvesting is prohibited in an area, sea urchin density would likely increase. sea urchin density is higher in marine reserves, probably as a result of decreased collection by commercial divers. although marine reserves predatory species such as sea otters and lobsters to thrive, there is only a slight effect on kelp. species diversity generally increases in marine reserves.

Answer;

- An increase in the number of predators in a community correlates with a decrease in the number of grazers (sea urchins in this case).

- Species diversity generally increases in marine reserves.

- Organism size increased by about 30% after the establishment of this reserve.

- Kelp forest recovery in marine reserves is likely due to an increase in predators.

Explanation;

-Biodiversity includes all the living organisms on earth, and in our parks we are finding plants and animals that have disappeared in other parts of the world due to development, habitat fragmentation, climate change, invasive species, and other threats.

.-National parks and other protected places are samples of the world's natural variety, often the last bastion of the earth's wild wealth. They are vital to our future well-being.

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
