- Give organisms of any ecological relationship that show competition and survival in the environment. After, explain how it is related to the statement "Survival of the fittest" of Charles Darwin.Primates are examples of: a. density-dependent species b. density-independent species c. r-selected species d. K-selected specieswhat kind of traits influence how a species contributes to a community? give an example TIA!!
- Describe how a researcher would determine the size of a penguin population in Antarctica using the mark and release method.Suppose two species of morning glories are reproductively isolated because in one species the flowers bloom in early April and in the other species they flower in mid-May. This would be an example of _______ isolation, which is a form of _______ isolation. a. habitat; prezygotic b. temporal; prezygotic c. temporal; postzygotic d. behavioral; postzygotic e. habitat; postzygoticWhich statement least applies to the concept of fitness? A. Measures of fitness include mating sucess and fecundity. B. It is trait featured among organisms which survived a bottleneck event. C. Reproductive sucess of individuals can be enhanced by their social behaviors within a group. D. Fitness among individuals in a population can vary due to differential reproduction.
- Describe Reproductive based on adaptation and speciation. Give a real world example.Which level of organization describes the interaction between populations of various species in an environment?Imagine two populations of penguins live in the same ecosystem. One population begins to exchange stones as a mating ritual while the other population begins to dance by shifting from one foot to the other. Individuals from each population will only mate with individuals that display the appropriate mating ritual. Which type of reproductive isolation mechanism does this scenario describe? Geographic Isolation Habitat Isolation Temporal Isolation Behavioral Isolation
