Answer:
The soil air is responsible for influencing the availability of many nutrients. Soil air is also by many of the microorganisms that release plant nutrients to the soil. The soil air can fill soil pores as water drains or is removed from a soil pore by evaporation or root absorption.
Explanation:
Answer:
e. Because gene flow between populations prevents genetic divergence in sympatry.
Explanation:
Speciation requires genetic divergence between populations of a species to isolate them reproductively. however, when present in the same habitat, gene flow between populations of a species does not allow their reproductive isolation and thereby, prevents the formation of new species. These populations need strong episodes of disruptive selection for their reproductive isolation.
On the other hand, two geographically isolated populations can not interbreed and thus, there is no gene flow between them leading to their genetic divergence and speciation. So, allopatric speciation is more common than sympatric one.
Answer:
it should be important because Energy needs to be transferred through an ecosystem to support life at each trophic leve.. hope this helps
Explanation:
Marshes give off saturated soil: "Marshes, also known as wetlands, are frequently inundated (flooded) with water. Plants found in marshes such as the common cattail, lily pads, and duckweed are adapted to the saturated soil conditions. Animals commonly seen in a marsh are otters and muskrats. There are many different types of marshes including coastal, inland, fresh water, salt water, riparian, and more. Marshes get their water from surface water (rain/runoff) and ground water." (Gundersen Envision,p.1)
They have plants and food for living animals there to eat.
There are fish for humans to use as food for.
They Drain common water from floods.
Most have fresh water (Meaning its drinkable)
