Which human activity would decrease the biodiversity of a wetland?
Other human acitivities which can have lasting effects on wetland ecosystems include stream channelization, dam construction, discharge of industrial wastes and municipal sewage (point source pollution) and runoff urban and agricultural areas (non-point source pollution).
What would be the effects of the changes in the river ecosystem?
More frequent droughts and shifting precipitation patterns lower water levels in rivers, lakes and streams, leaving less water to dilute pollutants. Higher temperatures cause more frequent algal blooms and reduce dissolved oxygen levels, both of which can cause fish kills and do significant harm to ecosystems.
How do biodiversity affect the stability of an ecosystem?
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?
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.
How does an increase in biodiversity influence balance in 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.
Does a creek have a current?
Although most creeks are smaller than a river, there are several creeks that are in fact larger and longer than some rivers and have stronger currents too. … Rivers flow in channels and have branches or tributaries while creeks do not. 3.
What is a small river that flows into a bigger river called?
tributary
A tributary is a freshwater stream that feeds into a larger stream or river. The larger, or parent, river is called the mainstem. The point where a tributary meets the mainstem is called the confluence. Tributaries, also called affluents, do not flow directly into the ocean.Apr 18, 2013
