what can cause a decrease in soil quality of farm land that is left without crops during some months every year

Answer:

Let the land lie fallow for a season

Explanation:

In Agriculture when a farmer has some problems with the quality of his soil due to continued planting all year round without allowing the soil rest, there seems to be loss of some of the nutrients that help crops grow and he is unable to grow crops on his field.

The best option is to allow the land low fallow with grasses and other plants growing and replenishing the soil.

Houses have been built around a small retention pond, increasing the fertilizer runoff into the pond. This has led to algal blooms in the pond which periodically reduce the amount of dissolved oxygen available in the water. What will be the most likely long-term effect on the fish population living in the pond if the situation with the fertilizer does not change?

The fish population will grow as more offspring are born that can take advantage of the new conditions.
The population will be replaced by a different species of fish that consumes algae for food.
The fish population will learn to survive with less oxygen and more algae in the water.
The population will evolve, leaving only those genetically equipped to deal with low oxygen levels.

Many tree frog populations are threatened due to habitat loss. In an effort to promote conservation, tree frogs may be bred in captivity. A zoo acquired male and female tree frogs from two different populations. In the zoo, the tree frogs were able to successfully mate within their own population, but breeding attempts between the two populations were unsuccessful.

Based on this information, which statement correctly describes the relationship between the two populations of tree frogs?

A.They are in the same species but different kingdoms.
B.They are in the same genus but different species.
C.They are in the same family but different orders.
D.They are in the same class but different phyla.

A small creek runs through a mature forest, keeping the soil around the creek damp all year. A variety of ferns and several flowering plants thrive in this shady, moist area. Along the higher ground above the creek, many species of flowering plants that need less water grow. If a farmer diverted the creek to water his fields, causing the creek to dry up, what would be the most likely long-term consequence for the ferns and angiosperms in the forest?

The ferns would outcompete the angiosperms in the forest since they can tolerate a wider range of moisture conditions than angiosperms.
The angiosperms and the ferns would not be affected since their thick, waxy cuticle coverings would protect them from drying out.
The angiosperms would outcompete the ferns since their sperm do not need moist conditions to get to their eggs as ferns do.
The ferns and angiosperms would begin to produce spores instead of seeds since the spores are better able to survive dry conditions.
