The correct answer is - Silurian period.

The eurypterids, initial jawed fish, and the vascular plants, are all supposed to have first evolved during the late Ordovician period, but in the fossil records they all start appearing in the Silurian period.

The Silurian period is a period in which there's enormous diversification in the animals and plants, with the bigger and more complex ones quickly developing and dominating the Earth. It is in this period that the ancestors of the later land animals appeared, though initially in the water, as well as the plants that covered the Earth and ever since than had been a key factor for the existence and development of the animals on the Earth.

What is a way to prevent eutrophication?
Anon25 [30]

Answer:

Agricultural fertilizers are one of the main human causes of eutrophication. Fertilizers, used in farming to make soil more fertile, contain nitrogen and phosphorus. The use, or overuse, of fertilizers can cause these nutrients to runoff of the farmer's field and enter waterways. Eutrophication can have serious effects, like algal blooms that block light from getting into the water and harm the plants and animals that need it. If there's enough overgrowth of algae, it can prevent oxygen from getting into the water, making it hypoxic and creating a dead zone where no organisms can survive.

The following is a list of methods that can be used to control eutrophication:

planting vegetation along streambeds to slow erosion and absorb nutrients.

controlling application amount and timing of fertilizer.

controlling runoff from feedlots.

The best, easiest, and most efficient way to prevent eutrophication is by preventing excess nutrients from reaching water bodies. This can be done in a number of ways, the simplest of which is just being aware of the chemicals and fertilizers that we are using.

Is a process in which a water body acquires high levels of nutrients
erik [133]
Eutrophication, the process by which a body of water acquires a high concentration of nutrients, has become known to the environmentally aware community as a key human stressor on the world's ecosystems. High concentrations of nutrients, specifically phosphates and nitrates, promote excess growth of primary producers.
