Ecology

The genetic variation within and among species in an ecosystem

The amount of biomass in an ecosystem

The number of individuals in a population

The total number of species in an ecosystem

A keystone species is one that is used as a symbol to raise awareness of conservation efforts, while a flagship species is essential to the functioning of an ecosystem

A keystone species is a rare and endangered species, while a flagship species is common and widespread

A keystone species is an indicator of ecosystem health, while a flagship species is a predator at the top of the food chain

Counter-current heat exchange in extremities of predators

Camouflage adaptations that allow prey animals better concealment from predators on snow-covered ground

Seasonal migration patterns of prey animals to warmer regions

Development of larger jaws in predators for increased bite force

Enlargement of physical structures like claws or teeth to dominate other animals.

A flexible behavior that allows for learning new responses to environmental changes.

Synthesis of toxins for defense against an increased number of predators.

Development of specialized feeding habits for exploiting one abundant resource.

It could enhance genetic variability in plants by promoting cross-pollination between different species.

It could decrease plant biodiversity due to overconsumption leading to the decline of certain plant species.

It may increase animal biodiversity by providing more food resources for higher trophic levels.

It would stabilize predator populations through increased predation on the insects.

It reduces because it encourages monoculture planting practices.

It increases by promoting plant reproduction and genetic variation.

It decreases as it leads to over-reliance on specific pollinators.

It remains constant as it only affects existing species interactions.

Indicating greater protein sequence similarities between products encoded by these genes.

By showing identical DNA sequences for both genes in all individuals examined.

Through higher mutation rates observed in the DNA sequences near each gene.

By displaying fewer recombinants between them during crossing over events.

Genetic drift following a founder effect can rapidly fix advantageous traits within isolated populations.

Stabilizing selection can maintain genetic diversity until an extreme phenotype becomes advantageous.

Disruptive selection encourages extremes in traits, potentially leading to two distinct phenotypes within one population.

Directional selection continuously favors individuals with more extreme versions of a trait over time.
