A decrease in biodiversity causes a decrease in ecosystem stability, because a change to one organism will have a greater impact on the entire ecosystem. With greater biodiversity, the loss of one type of organism could be moderated by the adaptation of other organisms to fill its role.
What will happen to an ecosystem with low biodiversity?
Declining biodiversity lowers an ecosystem’s productivity (the amount of food energy that is converted into the biomass) and lowers the quality of the ecosystem’s services (which often include maintaining the soil, purifying water that runs through it, and supplying food and shade, etc.).
What does low biodiversity mean for an ecosystem?
Low biodiversity is when there are a few prominent species and a low number of other species within the habitat. High biodiversity is a habitat or ecosystem that has a high number of different species.
What effect does biodiversity have on an 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.
How does biodiversity affect the stability of an ecosystem quizlet?
How does biodiversity affect the stability of an ecosystem? Having a number of different organisms increases the stability of an ecosystem, because a change in the population of one organism will have less effect on the population of an organism that depends on it.
How biodiversity can have a negative effect on the sustainability of an ecosystem?
Loss of biodiversity appears to affect ecosystems as much as climate change, pollution and other major forms of environmental stress, according to results of a new study by an international research team. … Studies over the last two decades demonstrated that more biologically diverse ecosystems are more productive.
Which of the following ecosystem is having low diversity?
Because little to nothing grows in ground that is frozen year-round except for some forms of microscopic life, the arctic biome has the least amount of diversity among all the major ecosystems of the Earth.
What is the main reason for having low biodiversity?
Biodiversity loss is caused by five primary drivers: habitat loss, invasive species, overexploitation (extreme hunting and fishing pressure), pollution, climate change associated with global warming. In each case, human beings and their activities play direct roles.
What does low diversity mean?
Firstly, low biodiversity means that the trophic system is likely less functional. Since there are less species in the various tropic levels, meaning the paths of energy and nutrients are fewer in number. … High biodiversity is like a bed of nails, except the nails are what’s keeping the ecosystem alive.
What is the advantage of high biodiversity over low biodiversity?
Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.
How does high biodiversity affect an ecosystem quizlet?
How does biodiversity affect ecosystems? The number and variety of species in an ecosystem can influence that ecosystem’s stability, productivity, and value to humans. … The number of species in those habitats drops, and some species may become extinct.
When might an increase in biodiversity lead to a decrease in the stability of an ecosystem ??
When might an increase in biodiversity lead to a decrease in the stability of an ecosystem? An increase in biodiversity usually leads to an increased stability, but in the case of an invasive species it would lead to a decreased stability.
