Biodiversity is the term used to describe all types of life and all organisms in the natural world Humans are the number one threat to biodiversity especially when it comes to climate change A change in habitat a change in the climate and a decrease or influx of any one species are the three main factors which determine biodiversity.

. The term invasive is poorly defined and often very subjective Invasive species may be plants animals fungi and microbes. Survival of the fittest. A reasonable explanation for this difference is that urban ants evolved higher heat tolerance over.

Phenotypic plasticityA term used to describe the ability of a species or ecotype to express different characteristics such as flower color leaf size or shape and tolerance of site conditions. NaturalizedA term used to describe a species that is not native to an area but has established a sustainable population in that area. The term that is now often used to refer to the clade that includes both humans and great apes that is chimpanzees bonobos gorillas and orangutans.

In contrast antagonism is the term used to. A species is defined as individuals and populations that can potentially interbreed and produce fertile offspring see Chapter 7. The word ecosystem is a generic term that is used to describe one or more communities of organisms that are interacting with their environment as.

Genes hold the key to survival. Ecological Balance and Its Importance. The more diverse genes a species has the better its chances of resisting disease prevailing over other stresses and adapting to changing conditions.

At best the ethics of this impact are questionable. Nearly every step in human history has unfortunately been accompanied with a leap in environmental degradation. In recognition of these changes we have introduced the term non-human hominids in place of great apes in most places.

Instructions tt Use black ink or ball-point pen. All living things on this planet interact in one way or another with other living things. The ongoing growth in human population and resource consumption is changing the planet in fundamental ways.

Environmental Science deals with the study of processes in soil water air and organisms which lead to pollution or environmental damages and the scientific basis for the establishment of a standard which can be considered. The Natural Environment and Species Survival Wednesday 25 January 2012 Morning Time. 5 little to no difference.

The results from Angillettas observational experiment show that urban ant populations have higher heat tolerance than rural ant populations. Ecological balance is a term used to describe the equilibrium between living organisms such as human being plants and animals as well as their environment. If both species benefit from interacting with each other that is if each species relies on the other one for its well-being then the relationship is called mutualism.

May 9 2015 Donna Thompson. In sexually reproducing organisms species consist of individuals that can interbreed with each other. An ecological niche is a term used by ecologists to describe the role a species plays in an ecosystem.

We use different terms to describe the interactions between two different species. This leads to competitive exclusion overlapping niches and resource partitioning. 3 urban slightly less than rural.

Fill in the boxes at the top of this page with your name tcentre number and candidate number. A term that refers to the survival of only those organisms best able fittest to obtain and utilize resources resulting in the evolution of organisms that are best adapted to the environment. The term coevolution is used to describe cases where two or more species reciprocally affect each others evolution.

It studies the sources reactions transport effect and fate of a biological species in the air water and soil and the effect of and from human activity upon these. Photosynthesis that takes place in ecosystem contributes to building a good environment that stabilizes the coexistence of all. 4 urban less than rural.

One species is compromising Earths ability to support the living systems that evolved on the planet over millions of years. The term hominoid is also no longer routinely used for great apes. The niche is affected by biotic and abiotic factors.

Ecological niches are affected by interspecies competition. One consequence of this growth is the loss of biodiversity which is typically estimated either by the net movement of species towards higher categories of extinction risk or as the rate at which species are actually going extinct. Some also include native species that have invaded human.

Species diversity is another term for biodiversity or the variety and richness of life in a habitat or ecosystem. So for example an evolutionary change in the morphology of a plant might affect the morphology of an herbivore that eats the plant which in turn might affect the evolution of the plant which might affect the evolution of the herbivoreand so on. At first humans were incredibly in-tune with their surroundings.

For example an ecotype that is only able to grow in wet soil. Evolutionary adaptation or simply adaptation is the adjustment of organisms to their environment in order to improve their chances at survival in that environment. The habitat of a moth species included trees with both light and dark colored barkTherefore the moth species included both light and dark colored variantsThen the light-colored trees were wiped out by a disease and within a few years nearly all the moths in this forest were dark colored.

Over time species have developed traits to help them flourish in their natural environment and survive in changing environments. The size of populations changes the amount of one species which can make the environment more or less diverse. The systematic reduction in Earths capacity to support life which Woodwell 1990 termed biotic impoverishment is thus the most important human-caused environmental impact.

Learn how to define species. A new analysis spanning more than 86000 plant species finds that on this human-dominated planet many more species of plants are poised to lose rather than win T A new analysis spanning more. Alien or naturalized species are those species which are not native to an area but established and those that are a threat to native species and biodiversity are often called invasive species.
