This predator should shift its feeding focus to- 22) A grass species affects temperature, moisture, sunlight input, and consequently creates new ecological niches due to its high population density. How would you describe the role of this grass species? Carrying capacity speciles Foundation species Dominant species Engineering species Keystone species 23) Your conservation biology team has received funding to accelerate primary succession in a severely disturbed habitat. What action would be the most beneficial? Add autotrophs Add nutrients Add heterotrophs Add water None of the above 24) What disturbance has selected for tree speciles that maintain most of their biomass underground? Tornado 25) According to the area effect hypothesis- Primary producer populations typically are stable over generations Secondary consumers limit the density of primary consumer populations A small stream has fewer species compared to stream larger in size Dominant species removal increases the total number of species Dominant species removal decreases the total number of species

Explanation / Answer

1. Answer is none of above because all species has special character that provide them defencive capability against predator. So in starving condition, its not easy for predator to find these species.

2. Answer is foundation species that effect and modify environment and maintain habitats that benifits other organism.

3. After disturbance in primary succession lichens are spread on rock that break down rock and slowly mosses and fern grow, soil layer thicken to hold water then small plant develop and further development occur. So the answer is none of above because water we will add after lichens, fern and moss development.
