B. A balanced
Explanation:
In a balanced ecosystem decomposers breakdown dead or decaying organisms and they return nutrients to the soil to be used by plants.
A balanced ecosystem maintains an equilibrium between the biotic component and abiotic component of the system.
- The nutrient cycling between biotic component and abiotic part of the ecosystem is kept going by decomposers.
- Decomposers are organisms that breaks down dead and decaying organisms.
- They release the nutrients trapped in them in the process.
- The nutrient in the soil is in its abiotic state.
- When plants takes up the nutrient, it enters back into the biotic component.
- Decomposers helps to maintain the balance in the ecosystem.

Answer:
E. They decrease the rate at which Ras hydrolyzes GTP.
Explanation:
Activated Ras has GTP bound to it, this propagates an intracellular signal to the nucleus where cell proliferation is induced. Thereafter proliferation is switched off by the hydrolysis of the bound GTP to GDP.
Therefore decreasing the rate of GTP hydrolysis causes Ras to remain active, ultimately leading to uncontrollable proliferation characteristic of cancer.
