A. network B.Trophic diagram C.Food Chain D.Food diagram

2. The persistence of Candida zemplinina in botrytized wine fermentation occurred because:

A. Saccharomyces preferentially uses glucose to avoid competition with the fermenting yeast

B. Saccharomyces preferentially uses fructose to avoid competition with the fermenting yeast

C. zemplinina preferentially uses glucose to avoid competition with the fermenting yeast

D. zemplinina preferentially uses fructose to avoid competition with tht fermenting yeast

3. The concept of _______________ suggests that predators can have a profound impact on species diversity in a community by keeping prey below their carrying capacity.

A. keystone species B.cornerstaone species C.food webs D. trophic networks

Answer 1

1C) Food Chain

Food chain refers to the sequence of events in an ecosystem, where one organism eats another and then is eaten by another organism. It starts with the primary source like the sun or hydrothermal vents where producers make food, continues with consumers or animals who eat the food, and ends with the top predator.

2B) S. cerevisiae consume fructose efficiently to avoid competition.

3A) Keystone Species. A keystone species is often a dominant predator whose removal allows a prey population to explode and often decreases overall diversity.
