Parasitism
An organism could be affected by a DNA mutation in various ways, such as changes in physical characteristics, susceptibility to diseases, or altered metabolic processes. The specific effects depend on the location and nature of the mutation in the organism's DNA.
The concentration of a substance such as a pesticide in the body of an organism is called "bioaccumulation." This process occurs when an organism absorbs a toxic substance at a rate faster than it can eliminate it, leading to higher concentrations of the substance in its tissues over time. Bioaccumulation can have harmful effects on the organism and can also impact the food chain and ecosystem.
The concentration of nerve tissue and sensory organs is typically higher at the anterior end of an organism, as this region is involved in gathering information from the environment and coordinating responses. This concentration allows for quicker detection and processing of stimuli to aid in survival and navigation.
An organism can be affected by its environment, other organisms, and genetic factors. These interactions can include competition for resources, predation, symbiotic relationships, and the expression of different traits determined by genetic makeup.
descride how an organism of your choise is negatively affected by human activity
When one species is affected negatively and one is not affected.Amensalism an ecological study which states that when an organism is benifiting but none is affected nor benefiting but just steady
In commensalism, one organism benefits while the other is unaffected, whereas in ammensalism, one organism is unaffected and the other is negatively affected.
It would depend completely on the types of species in question. Some possible effects could be: 1) Mutualism --> both benefit from one other. 2) Predation --> one species benefits while the other suffers. 3) Neutralism --> despite interaction, there is no overall affect on either species. 4) Competition --> both species are negatively affected by the other. 5) Commensalism --> one species benefits while the other is unaffected. 6) Amensalism --> one species is negatively affected and the other is not affected.
The first organism affected would be the algae living in local water-ways. The fertilizer run-off causes an algal bloom. This algal bloom uses increased amount of oxygen taken from the water therefore the first organism negatively affected would be organisms in the water surviving on oxygen. More than likely it would be the earthworms under the rows of crops; they would be affected almost immediately after the water hits the ground.
I would think an aerobic organism would do the worst in an oxygen poor media, which would be one of the results of having an older media sitting around.

If an animal on a high trophic level eats other organisms on a lower trophic level effected by DDT, the animals level will be affected.
Just about ALL human (and living organism) characteristics are affected by genes.
The central nervous system is affected.
