During his travels, Darwin made numerous observations and collected evidence that led him to propose a revolutionary hypothesis about the way life changes over time.
His travels revealed to him that there may be a species with a high population the species will have a big variety of organisms according to which group of them live where.
A gradual development of life forms over time.
Fitness is generally measured in average number of fertile offspring.
This is called the hierarchy of biological classification., going from most member to a specific member. Staring with the most general: life, domain, kingdom, phylum, class, order, family, genus, species.
There are a number of species that utilize electricity in order to hunt their prey or to defend them selves. Electric eels living in freshwater are quite amazing and can give shocks of several hundred volts. Some flat fish living in Salt Water does also have this ability but their power is not comparable to that of the Electric eel. In fact all living species does conduct electricity one way or another. All brains in living creatures function by sending electric signals back and forth. When you read this, the light is interpreted by eyes and in turn transformed into an electric signal that is further processed by the brain. When you decide to type an answer here on WikiAnswer, it is electrical signals from your brain that makes your arms, hands and fingers move. Did you know that the Human Brain actually uses up approx 30% of all the energy provided by food :-) Most of which is transformed into electricity to keep our "computer" running.

Biodiversity is the measure of the number of species living within an ecosystem.
species of all six kingdoms living within an ecosystem.
Biodiversity refers to the number and variety of species that live in a specific area. It encompasses not only the diversity of species, but also genetic diversity within each species and the variety of ecosystems present.
I believe it is biodiversity.
Biodiversity measures the variety and variability of life forms within a given area. It includes diversity at the genetic, species, and ecosystem levels.
Biodiversity is the variety and number of species in a given area.
Biodiversity refers to the variety and variability of living organisms within an ecosystem. It can include genetic diversity, species diversity, and ecosystem diversity. High biodiversity is important for ecosystem resilience and stability.
Actually, the rainforest supports the greatest number of species of plants and animals. The grasslands support a greater variety of species than the desert.
A population is a group of one species living in an environment. A community is a collection of these populations, and an ecosystem is the interactions of this community and the environment (biotic and abiotic factors).
Biodiversity is the variety of life on Earth. Biodiversity include the genetic variety among individuals in a species, the number of species in an ecosystem and the variety of ecosystems in the biosphere. The main factors causing the threat to biodiversity are pollution, habitat destruction, introduced species and overexploitation.
A 'population'.
