The introduction of a new predator, the spread of a new disease, the introduction of a toxic substance, or the elimination of a food source are all examples of environmental changes that could affect the survival of a species.
Biodiversity measures the variety and variability of life forms within a given area. It includes diversity at the genetic, species, and ecosystem levels.
The Latin meaning of biodiversity is the complete existence of species and genes in the ecosystem. All the organisms depend on each other for survival.
This is an example of an ecological concept known as interdependence. It occurs when the actions or presence of one species positively affect another, while negatively impacting a different species. This can lead to complex relationships within ecosystems where different species rely on each other for survival.
Biodiversity refers to the variety and variability of life forms within an ecosystem or a community. It encompasses different species, genetic diversity, and ecosystem diversity.
Innate behaviors are genetically programmed and passed down through generations within a species. They provide a survival advantage or aid in reproduction, so individuals within the same species share these behaviors to increase their chances of survival and successful reproduction. This shared trait enhances the overall fitness of the species.
It is a diversification of traits within a species. An example of this is ladybugs with different numbers of spots.
Natural selection affects the survival of individuals within a species. Individuals with advantageous traits that better suit their environment are more likely to survive and reproduce, passing those traits onto the next generation. Over time, this can lead to changes in the species as a whole.
Biodiversity measures the variety and variability of life forms within a given area. It includes diversity at the genetic, species, and ecosystem levels.
The evolutionary process results in the adaptation and diversification of species over time to optimize their survival and reproduction in a changing environment. This process is driven by natural selection, genetic drift, and other factors that shape the genetic variability within populations.
Genetic variability refers to the differences in DNA sequences among individuals in a population. This variability is essential for evolution as it allows for adaptation to changing environments and the development of diversity within species. Genetic variability can arise from mutations, genetic recombination, and gene flow.
minimizes the within-class variability while at the same time maximizing the between-class variability.

A gradual development of life forms over time.
Biodiversity refers to the variety and variability of life forms within an ecosystem or a community. It encompasses different species, genetic diversity, and ecosystem diversity.
The long-term survival of a species depends on having access to essential resources like food, water, and shelter. If these resources become limited from time to time due to factors like environmental changes or human activities, it can lead to competition among individuals within the species. This competition for limited resources can affect reproductive success, population growth, and overall resilience of the species, potentially jeopardizing its long-term survival.
Because there is variation within a species, it is therefore possible for the law of natural selection to operate, by selecting those variations which best enhance survival and reproduction.
