katovenus [111]

The correct answer is:

Grow a legume crop to support the development of root nodule

The best way that a farmer could increase the amount of nitrogen in his fields without adding synthetic fertilizer is to grow a legume crop to support the development of root nodules. This is because legumes have a symbiotic relationship with bacteria found in the soil. 

Explanation:

Legumes use nitrogen fixing bacteria, specifically symbiotic rhizobia bacteria, within their root nodules to counter the limitation.The plant root cells convert sugar into organic acids which then supply to the rhizobia in exchange, hence a symbiotic relationship between rhizobia and the legumes.

Who is most in danger from the effects of overfishing ?
faltersainse [42]

I don't think we can answer this question just like that. The question should be formulated a bit differently:

WHAT is in danger from the effects of overfishing?


Well, in the end of the "effect-spectrum" we are in danger, since we also eat fish. But the most affected species are the ones that form the aquatic ecosystems. Such as fish. Examples:

1 - Many of the fish we eat, feed on sea-weed. If there aren't enough fish to eat the growing population of sea-weed, many fish die of intoxication.

2 - We don't have almost any fish restrictions in a way, because we can eat basically all of them. Therefore, many fish (which are also being eaten) find themselves in a lack of food.

3 - Many times, we concentrate on a specific species, which is a main cause of the extinction of species.



Hope it helped,
