Which do you think has more of an influence in shaping an ecosystem GPP or NPP?
Gross Primary Productivity is the total energy made to be used by plants, the Net Primary Productivity is this energy minus energy lost in respiration. Net Primary Productivity has more of an influence, because it is the amount of actual consumable energy.
Which can have the most impact on an ecosystem?
A biome is a large group of plants and animals living together in a specific _____. Which type of pollution is believed to have the most impact on an ecosystem? … Unnatural occurrences can have the most significant impact on an ecosystem.
Which of the following is a factor that would influence ecosystems?
They include factors such as light, radiation, temperature, water, chemicals, gases, wind and soil. In some environments, such as marine environments, pressure and sound can be important abiotic components.
What factors do you think influence how resistant an ecosystem is?
Environmental resistance factors are things that limit the growth of a population. They include biotic factors – like predators, disease, competition, and lack of food – as well as abiotic factors – like fire, flood, and drought. The biotic potential of a population is how well a species is able to survive.
How does temperature affect NPP?
The effect of temperature change is generally positive to increase the productivity by enhancing the photosynthesis as long as the temperature is in a range of optimum level. When temperature exceeds the optimum level, it will increase the rate of respiration causing the NPP continuously declined.
Which terrestrial and aquatic ecosystems have the highest NPP?
The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts. In aquatic…
What are the 5 major impacts humans have on the environment?
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Which factor S can influence continual change in an ecosystem?

What can impact an ecosystem?
Wind, rain, predation and earthquakes are all examples of natural processes which impact an ecosystem. Humans also affect ecosystems by reducing habitat, over-hunting, broadcasting pesticides or fertilizers, and other influences. The line between natural and human caused effects often blurs.
Which of the following is a factor that would influence ecosystems quizlet?
4 different abiotic factors that effect an ecosystem are light , temperature, water, and soil. Soil can effect the ecosystem because the process of decay gives raw materials to the plants. Animals effect the ecosystem because when an animal needs something, it builds its habitat and it changes how everything works.
Are the most important three factors in ecosystem?
Biotic components include plants, animals, decomposers. Nonliving components include air, water, land.
Which ecosystem would you expect to have the highest resistance?
Which ecosystem would you expect to have the highest resistance? Which would have the highest resiliency? Why? Ecosystem C would have the hugest resistance because the organisms have adopted to the often disruptions in their ecosystem.
What are the environmental factors that influence the survival of organisms on ecosystem?
Some of the abiotic, or nonliving, factors that affect organisms’ ability to survive include temperature, light availability, soil type, water, salinity levels, pH levels, nutrient levels, topographical features and altitude.
How can increasing the diversity of species affect the ecosystem?
Increasing species diversity can influence ecosystem functions — such as productivity — by increasing the likelihood that species will use complementary resources and can also increase the likelihood that a particularly productive or efficient species is present in the community.
