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.
What is an example of a biotic factor that could affect a population?
Biotic factors refer to the living or once-living organisms in an ecosystem and their impacts such as predation, competition, food supply, human impacts and parasites. Environmental factors such as rainfall, climate, predators, shelter and food availability can change.
Which of the following is an example of a biotic factor can affect the population dynamics in an ecosystem?
Which of the following is an example of how a biotic factor can affect the population dynamics in an ecosystem? a. Lack of water during a drought causes many of the individuals in a population to die. … The population of a predator increases following an increase in the population of its prey.
Which is a biotic factor that can affect an ecosystem?
The biotic factors in an ecosystem are the other organisms that exist in that ecosystem. How they affect an individual organism depends on what type of organism it is. The other organisms (biotic factors) can include predators, parasites, prey, symbionts, or competitors.
How are fish a biotic factor?
A biotic factor is a living organism that shapes its environment. In a freshwater ecosystem, examples might include aquatic plants, fish, amphibians, and algae. Biotic and abiotic factors work together to create a unique ecosystem.
Which of these is an example of a biotic factor that could limit a community in an ecosystem?
Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment.
What are 5 biotic factors examples?
5 Answers. Examples of biotic factors include any animals, plants, trees, grass, bacteria, moss, or molds that you might find in an ecosystem.
Is shelter a biotic or abiotic factor?
Food, shelter, water, and sunlight are just a few examples of limiting abiotic factors that limit the size of populations. In a desert environment, these resources are even scarcer, and only organisms that can tolerate such tough conditions survive there.
What is an example of biotic or living conditions?
Biotic describes a living component of an ecosystem; for example organisms, such as plants and animals. Examples Water, light, wind, soil, humidity, minerals, gases.
Is soil a biotic or abiotic factor?
Soil Layers. Soil is composed of both biotic—living and once-living things, like plants and insects—and abiotic materials—nonliving factors, like minerals, water, and air. Soil contains air, water, and minerals as well as plant and animal matter, both living and dead.
Which is a biotic factor that could affect an ecosystem quizlet?
A biotic factor is any living component that affects the population of another organism, or the environment. This includes animals that consume the organism, and the living food that the organism consumes. Biotic factors also include human influence, pathogens and disease outbreaks.
How do biotic factors affect abiotic factors in an ecosystem?
A biotic factor is a living thing that has an impact on another population of living things or on the environment. Abiotic factors do the same thing, but they are non-living. … To survive, biotic factors need abiotic factors. In turn, biotic factors can limit the kinds and amounts of biotic factors in an ecosystem.
How biotic factors affect the distribution of organisms?
They can also influence the distribution of organisms in an ecosystem. grazing – too little leads to dominant plants outcompeting other species, too much reduces species numbers overall. Both decrease biodiversity. predation – a reduction in predators can lead to an increase in prey.
What factors affect fish population?
A fishery population is affected by three dynamic rate functions:
- Birth rate or recruitment. Recruitment means reaching a certain size or reproductive stage. …
- Growth rate. This measures the growth of individuals in size and length. …
- Mortality. This includes harvest mortality and natural mortality.
What factors affect fish growth?
Also, water level, turbidity, heavy rains or no frequent rains, air temperature, etc are some factors that affect the birth, growth, harvest and death in fishes . Some physical, chemical/biochemical factors like water temperature, pH, alkalinity, hardness, etc are important to fish growth and mortality  .
What three factors affect fish communities?
In essence, fish need suitable environmental conditions to live and reproduce. The existence of good fish habitat is dependent on a number of factors, such as water flow, water quality, the presence of sufficient food, and the lack of excessive numbers of predators and competitors .
