What causes bacteria to decrease?
Bacteria can decrease in number due to factors like lack of nutrients, changes in environmental conditions (such as temperature or pH), competition with other microorganisms, exposure to antibiotics or disinfectants, and the immune response of the host organism.
How would a significant decrease in the pH of rainfall be likely to affect the biodiversity among organisms in an ecosystem over time?
A significant decrease in the pH of rainfall, also known as acid rain, can lead to a decrease in biodiversity among organisms in an ecosystem over time. Acid rain can lower soil pH, affecting plant growth and reducing food sources for other organisms. It can also directly harm aquatic organisms living in bodies of water where the acidic rainwater flows. Over time, this can lead to a decrease in biodiversity as populations decline.
Why are higher levels of biodiversity good for ecosystem stability?
The higher the biodiversity, the higher the number of species, and the lower the rate of extinction. A decrease in biodiversity means a single species will become extinct and this will have a negative impact on other organisms for all organisms in an ecosystem are connected.
How does biodiversity contribute to overall health of an ecosystem?
The more variety and the larger the number of species living in an ecosystem, the better it is able to recover from a natural or man made disaster, i.e., the more producers that are present, the less likely that overconsumption of one part will have a permanent negative effect on the ecosystem as a whole.
What is the number of species living within an ecosystem is a measure?
Biodiversity is the measure of the number of species living within an ecosystem.
What does whales role in ecosystem mean?
the depletion of the number or whales will lead to the decrease in other sea life
What change to this food chain would most likely result from a decrease in the mouse population?
decrease the number of hawks

Why do you have to wash the human skin?
To remove surface contaminants (like dirt or sweat) and to decrease the number of surface bacteria living there.
Would most likely happen if the number of shrimp increase?
the plankton population would decrease
If the number of denitrifying bacteria decreased what effect would this have on the nitrogen cycle and what type of compound would accumulate as a result?
A decrease in denitrifying bacteria would lead to less conversion of nitrate (NO3-) into nitrogen gas (N2) during denitrification, disrupting the nitrogen cycle. As a result, nitrate levels would increase in the ecosystem, leading to potential water pollution and eutrophication in aquatic systems.
How would an ecosystem be affected by a decline in their numbers?
It could impact the ecosystem immensely. It would decrease the number of animals that feed off the producers, and then decrease the number of animals that feed off those animals etc. Its a massive chain, as soon as you change one little thing everything else changes
Biotic factor that affects the size of a population in a specific ecosystem?
Predation is a biotic factor that can affect the size of a population in a specific ecosystem. The presence of predators can limit the growth of a population by preying on individuals. This can result in a decrease in the population size.
What would happen most likely happen if the number of shrimp increased?
the plankton population would decrease
What actions do antibiotics have on severe cases of shigellosis?
In those with severe infections, antibiotics will decrease the length of symptoms and the number of days bacteria appear in the feces.
How many habitats in an ecosystem?
There is no certain number of habitats in an ecosystem because it depends on the number of organisms living in that ecosystem.
