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.
During his travels, it was revealed to him that an enormous number of species inhabit the Earth. He noticed that every place he went to had different animals that were suited for that environment. However, similar environments didn't always have similar species. There could be immense variations of the same species all over the world.

A gradual development of life forms over time.
Fitness is generally measured in average number of fertile offspring.
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.
individuals an ecosystem can support.
I can think of two examples off the top of my head: 1. He is a versatile actor. 2. Wood is a versatile material. Sentence number 1 means that "he" plays a variety of roles very well, and sentence number 2 means that wood has a variety of uses.

I believe it is biodiversity.
Biodiversity is the measure of the number of species living within an ecosystem.
Biodiversity is the variety and number of species in a given area.
Actually, the rainforest supports the greatest number of species of plants and animals. The grasslands support a greater variety of species than the desert.
The Tundra
species of all six kingdoms living within an ecosystem.
some factors that determine the number of species in an area. some factors that determine the number of species in an area.
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'.
The largest variety of species is in the insect family. The number of insect species outnumber all other families of species combined.
