Answer 1

1. The following which is involved in decomposition that connects all trophic levels is FUNGI.

Decomposers/ Detrivores derive their energy from detritus, non living organic matter and decomposition connects all trophic levels. These decomposers form a major link between primary producers and the consumers in an ecosystem. The organic matter in the ecosystem is recycled with the help of decomposers. The ecosystem main decomposers are Fungi which secrete enzymes that digest organic material and and then absorb the breakdown products.

2. Exponential growth of a population is represented by dN/dT = rN

Continuous population growth is called the Exponential Growth and this growth in an unlimited environment can be modelled exponentially with the equation

dN/dT = rN

dN/dT = change in population size (instantaneous growth rate)

r = Intrinsic rate of increase or Percapita rate of increase ( equals birth rate minus death rate)

N = Population size

The percapita rate of increase (r) doesnot change though population rate increases at a larger rate.
