What is an abundant species?
Species abundance is the number of individuals per species, and relative abundance refers to the evenness of distribution of individuals among species in a community. Two communities may be equally rich in species but differ in relative abundance.
What is the difference between distribution and abundance of species within an ecosystem?
Distribution refers to the region where an organism is found. Abundance is the number of individuals in the area. Both distribution and abundance can change seasonally or yearly. Abundance is usually described as density – the number on individuals in a certain area – as this gives an idea of crowding.
What is the relationship between abundance of a species and the geographic range of the species?
What is the relationship between abundance of a species and the geographic range of the species? Geographic range increases as abundance increases. Explain why researchers commonly find a relationship between adult body size and population density. Larger animals require more land to support their metabolism.
Why is temperature important for survival of living organisms?
Temperature. Temperature has the single most important influence on the distribution of organisms because it determines the physical state of water. Most organisms cannot live in conditions in which the temperature remains below 0 °C or above 45 °C for any length of time.
Is a dead log living?
Scientists are finding that dead wood is very much alive. Biologist Mark Harmon, also known as “Dr. Death,” studies the importance of dead trees to forests. A decaying log is a microscopic forest within a forest.19
Are eggs considered living?
The egg we get from a grocery shop is not alive as it is unfertilised egg. After hatching, the egg cell divides, grows and produces chick. These are the properties of living organism, so fertilised egg can be considered as living.25
