What will be the effect on biotic factors in the running water of river?

Fish food organisms will be highly affected by reduced flow rates and new species will invade areas with a slow current. ​​​​​​Flooding of surrounding habitat around the dams also kills the trees and other plants.

How does water affect the biotic factors?

Water is important to every organism. A great portion of chemical reactions that organisms use take place in water, so without water, organisms would not be able to metabolize anything. … Primary consumers (herbivores) would suffer twofold as their prey (the plants) die and their water source disappeared.

What are the biotic factors of a river?

For example in the river a biotic factor can be small frogs, plants, fish anything living in the river. In the sea the biotic factors are any large fish or sea creatures living in that area, also any small organisms like shrimp and other things you can see.

How do the abiotic factors affect the biotic factors in the ocean?

Biotic factors include plants, animals, fungi, algae, and bacteria. Abiotic factors include sunlight, temperature, moisture, wind or water currents, soil type, and nutrient availability. Ocean ecosystems are impacted by abiotic factors in ways that may be different from terrestrial ecosystems.

How does water affect organisms in an ecosystem?

The main function of water is to propel plant growth; provide a permanent dwelling for species that live within it, or provide a temporary home or breeding ground for multiple amphibians, insects and other water-birthed organisms; and to provide the nutrients and minerals necessary to sustain physical life.

Is water a biotic or abiotic factor?

Some examples of Abiotic factors are the sun, rocks, water, and sand. Biotic factors are living organisms that affect other living organisms. Some examples of Biotic factors are fish, insects, and animals.

How do biotic and abiotic factors interact?

Abiotic factors help living organisms to survive. Sunlight is the energy source and air (CO2) helps plants to grow. Rock, soil and water interact with biotic factors to provide them nutrition. Interaction between biotic and abiotic factors helps to change the geology and geography of an area.

What abiotic factors might affect a river ecosystem?

A stream is an example of a freshwater ecosystem. Abiotic factors are the nonliving components that form the environment in which the organisms subsist in a stream (freshwater ecosystem). These include factors such as light, current, temperature, substrate and chemical composition.

What abiotic factors might affect a river ecosystem quizlet?

Which is a biotic factor in the environment of a fresh water fish?

Explanation: Abiotic factors for fish is water, temperature, amount of dissolved oxygen in water, etc. Penetration of sunlight is also important in fresh water habitat. Biotic factors are predators, disease causing organisms, organisms available as food, population density of competitors, etc.
