Population and Community
Ecology
Population ecology is the study of the factors that affect the size and distribution of populations. Community ecology is the study of the interactions between different populations in an ecosystem.
Different Levels of an Ecosystem
There are many different levels of an ecosystem, starting with the tiniest creatures and ending with the largest. The levels can be divided into five different types: the abiotic environment, the biotic community, the population, the species, and the ecosystem.
The abiotic environment is made up of the non-living things in an ecosystem, such as the air, water, and soil. The biotic community is made up of the living things in an ecosystem, such as the plants and animals. The population is made up of all the members of a particular species in an ecosystem. The species is the most basic unit of classification for living things, and is made up of all the individuals of a particular kind of organism. The ecosystem is the highest level of an ecosystem, and is made up of all the living things and the non-living things in an area.
The Difference Between Species and Population
A species is a group of organisms that can mate and produce fertile offspring. A population is a group of organisms of the same species that live in the same area at the same time.
The Difference Between Population and Community
The difference between population and community is that a population refers to all the individuals in a given area that can potentially interbreed, while a community refers to all the different species of organisms that live in a given area.
Explain in detail :
The study found that women who reported higher levels of stress were more likely to have a child who was overweight or obese by the time they reached kindergarten.
The study looked at the stress levels of mothers when their children were 3 years old and then looked at the weight of those children when they reached kindergarten. The study found that the children of mothers who reported higher levels of stress were more likely to be overweight or obese.
The study did not look at the cause of the higher stress levels in the mothers, but it is possible that the stress caused the mothers to eat more or to be less active, which could lead to their children being overweight or obese.
