Autotrophic.

Dark reaction happens in the photosynthetic process of plants or autotrophs.
(a) A giant redwood tree = Autotroph
(b) A spider = Heterotroph
(c) A rose bush = Autotroph
(d) A mushroom = Heterotroph
(e) A blue whale = Heterotroph
Autrophs are the organisms that have the capacity to form their own food from inorganic substances like the carbon dioxide. 
Heterotrophs are the organisms that cannot produce their own food but depends on other animals or plants for their nutritional needs.

The growth of a population of sparrows accelerates with each generation. the chances of dying are about the same for these sparr

Paladinen [302]

Answer:

Exponential growth and a type II survivorship curve

Explanation:

Firstly we need to understand what exponential growth is, it is the type of growth in which population of any specie increases at a tremendous rate, constantly. In this type of growth, the increase is an exponential function of time for example, 2 reproduce to form form, four to sixteen and so on.

Population survivorship curves are simply the graphs representing increase in population with respect to time. There are three types of population survivor ship curve, Type I, Type II and Type III.

In Type II survivorship curve, there is a constant dying rate of individuals of population with respect to time.

Now lets come back towards question, where two characteristics of the population are mentioned,

Exponential growth of a population of sparrows with each generation.
Constant dying rate

This clarifies that Exponential growth and a type II survivorship curve is the best option representing the said scenario.

Hope it help!
