Most of the biomass in an ecosystem is made up of
Producers
Primary consumers
Secondary consumers

How do the continuous survival of peacocks conflict with Darwin’s model of natural selection?
According to Darwin, the large, bright feathers should increase a peacock’s chance of survival
According to Darwin, the large, bright feathers should decrease a peacock’s chance of survival
According to Darwin, the large, bright feathers should not affect a peacock’s chance of survival
How can Darwin's model of natural selection (survival of the fittest) explain organisms that evolve elaborate traits which are not beneficial to their individual survival? (ex: peacock)
The most fit organisms are the strongest and fastest in their population
The most fit organisms are those that can survive the longest
The most fit organisms are those that can survive and pass their traits on to the next generation
Sexual selection involves
Competing for the chance to find a mate
Trait variation between the different sexes
Characteristics that increase attractiveness
All of these
When we say that an individual organism has greater fitness than another individual, we specifically mean that the organism
Lives longer than others of its species
Competes better for food and resources
Has traits including speed and camouflage
Survives and reproduces more frequently
