Why is fish a biotic factor?

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.

Is fish a biotic?

Answer: Biotic: fish, plants, algae, bacteria. Abiotic: salt, water, rocks, sediment, trash.

Why is an animal a biotic factor?

Biotic components are living organisms in an ecosystem. A biotic factor is a living organism that affects another organism in its ecosystem. Examples include plants and animals that the organism consumes as food, and animals that consume the organism.

How are fish affected by abiotic factors?

Abiotic variables, such as total phosphorus, dissolved oxygen, and conductivity, determined the distribution of fish assemblages. Streams without urban influence exhibited intrinsically low species richness, suggesting that they are highly susceptible to species loss and diversity reduction.

What are the 5 A biotic factors?

Like all ecosystems, aquatic ecosystems have five biotic or living factors: producers, consumers, herbivores, carnivores, omnivores, and decomposers.

What biotic factors affect 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.

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 [26]. Some physical, chemical/biochemical factors like water temperature, pH, alkalinity, hardness, etc are important to fish growth and mortality [33] .

Are animals biotic?

Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere.

Is grass biotic or abiotic?

Grass is a biotic component of the environment. Biotic factors are the living components of an ecosystem.

Are humans biotic factors?

Humans are also biotic factors in ecosystems. Other organisms are affected by human actions, often in adverse ways. We compete with some organisms for resources, prey on other organisms, and alter the environment of still others.

How do abiotic factors affect biotic factors in an aquatic ecosystem?

Abiotic factors are parts of an environment that are not alive, but that affect the ecosystem. Factors that affect aquatic ecosystems include water flow rate, salinity, acidity, oxygen, light levels, depth, and temperature. Light levels affect photosynthesizing plants and predation.

What abiotic factors that affect the fish appetite?

chemo-attraction, vision, electrosensory and mechanoreception systems, social interactions and prey avoidance behavior and abiotic factors like light and day length, temperature, water quality and physical properties of the food have shown the effect on the feed intake.

What factors can affect fish that live in a pond?

Fish production can be greatly affected by excessively low or high pH. Extreme pH values can even kill your fish. The growth of natural food organisms may also be greatly reduced. The critical pH values vary according to the fish species, the size of individual fish and other environmental conditions.

Is hair abiotic or biotic?

Hair is biotic because it was living at one time. The root of the hair that is in your skin is alive.

Is plankton biotic or abiotic?

Moreover, the phytoplankton community acts as a biotic influence and interacts with the bacterial community through direct or indirect interactions including mutualism, commensalism, parasitism, amensalism and competition (Kazamia et al.

Which is an example of 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.
