b and e kills organisms, so it doesn't evolve the diseases. genetic modification causes the plants to be resistant, and doesnt target diseases, so the disease isnt evolved. only antibiotics make diseases evolve, overuse of it causes the disease to develop resistance if it isnt completely killed off.
Ecosystem includes all of the biotic and abiotic factors that are found in a given environment. Biome is a collection of different ecosystems which share similar climate conditions.
The natural grassland ecosystem is known for its relatively high net primary productivity and high trophic efficiencies compare to other types of ecosystem, many reasons are responsible for this and three of them are listed below:
1. Natural grassland are regionally adapted to survive environmental fluctuations and grazing pressure.
2. The diverse producer base of the natural grassland ecosystem results in a large number of trophic connections. This enhances energy transfer and reduces energy losses.
3. Nutrient cycling in the natural grassland ecosystem is very efficient and this contributes to the overall efficiency of the ecosystem. The recyclers in the ecosystem decompose dead organic matters and release the energy trapped inside them.
