Question
Can you help me with these questions please Under controlled laboratory conditions, you added two microbial species to the same nutrient solution. Within one week, only one microbial species remained. This observation relates to - Keystone Species Hypothesis Competitive Exclusion Carrying Capacity Resource Partitioning Dominant Species Hypothesis Three related lizard species are members of a forest community In Norfolk. What enables these related lizard species to co-exist In this forest community? Mutualistic Partnership Resource Sharing Competitive Exclusion Resource Partitioning None of the above The white stripe on the back of an otherwise black skunk Is an example of - Misidentification Warning Coloration Mullerian Mimicry Batesian Mimicry Masquerade
Explanation / Answer
Answer 1: Among two microbial species in the same nutrient species one survived .This is called compititive exclusion also known as gause's law. When tow organisms need the same resoure for thier existance, the dominant will survive. Other options are not right because it means the the survival of both species by dividing the nutrient media, which is not possible in case of microbial species.
Key stone species are those which helps to understand entire ecosystem. This is irrelevant answer to the subject.
Answer 2: The right answer is resource patitioning. Lizards always prtition their living niche and dwell in different microhabitats.
Answer 3: The white stripe on black skunk is a kind of warning coloration. The predators are attracted towards the stripes that point to the anal gland. skunk sprays anal gland secretions over predators and escape.
It cant be other options because mimicry are the resembling sounds which has nothing to do with the stpies of skunk. Masquerade is a kind of disguising and pretending to be something else.
