The cell membrane is a selectively permeable membrane which controls what goes in and out to ensure that not just anything comes in through it's own accord.
Answer:
The correct choice is A)
There will be fewer producers in the area.
Explanation:
Very easy to deduce. A producer in biology of ecosystems is an organism that produces its own food. Another word for a producer in biology is 'autotroph'.
They produce energy directly from the energy given off by the sun or chemicals or both.
Grass (or plants) are producers. They do this with the help of water, converting solar energy into sugar or food, which are usable forms of energy.
So the more grass is consumed, the fewer producers in the area.

The correct answer is all of these.
Matter and energy on Earth are never destroyed or created out of nothing, but just transferred or converted to another form.
The inorganic matter is transferred to the living things from the physical environment by many biological processes like photosynthesis ( CO2), nitrogen fixation, absorption of the minerals by plant roots and many more.
Matter can then be transferred between different organisms through the food chain.
Eventually, the matter will return to the physical environment when organisms decompose and the cycle will start again.
