Chapter 9 Test Review Interactions of Living Things Answers

Biotic and abiotic are the two essential factors responsible for shaping the ecosystem. The biotic factors refer to all the living beings present in an ecosystem, and the abiotic factors refer to all the non-living components like physical conditions (temperature, pH, humidity, salinity, sunlight, etc.) and chemic agents (different gases and mineral nutrients present in the air, h2o, soil, etc.) in an ecosystem. Therefore, both the abiotic and biotic resources affect survival and reproduction process.

Furthermore, both these components are reliant on each other. Suppose if one of the factors is removed or contradistinct, its repercussions will exist faced by the entire ecosystem. Without a doubt, abiotic factors directly bear on the survival of organisms. Read on to explore what role do abiotic and biotic resource play in the ecosystem.

Biotic Meaning

The term "biotic" is formed past the combination of two terms, "bio"meaning life and"ic"pregnant like. Thus, the term means life-like and is related to all the living entities present in an ecosystem.

Biotic Factors

Biotic factors chronicle to all the living things  in the ecosystem. Their presence and their biological by-products affect the composition of an ecosystem. Biotic factors refer to all living organisms from animals and humans, to plants, fungi, and leaner. The interactions between diverse biotic factors are necessary for the reproduction of each species and to fulfil essential requirements like food, etc.

Examples of Biotic Factors

Examples of biotic resources include all the living components present in an ecosystem. These include producers, consumers, decomposers and detritivores.

Abiotic Meaning

The term abiotic refers to all the non-living factors nowadays in an ecosystem. Sunlight, water, land, all constitute the abiotic factors.

Abiotic Factors

Abiotic factors refer to all the not-living, i.e. chemical and physical factors present in the atmosphere, hydrosphere, and lithosphere. Sunlight, air, atmospheric precipitation, minerals, and soil are some examples of abiotic factors. These factors have a significant touch on on the survival and reproduction  of species in an ecosystem.

For instance, without an adequate amount of sunlight, autotrophic organisms may not exist able to survive. When these organisms eventually die, information technology will create a shortage of food for main consumers. This result cascades upward the food concatenation, affecting every organism. Consequently, it leads to an imbalance in the ecosystem.

Examples of Abiotic Factors

Abiotic examples typically depend on the blazon of ecosystem. For case, abiotic components in a terrestrial ecosystem include air, atmospheric condition, h2o, temperature, humidity, distance, the pH level of soil, blazon of soil and more. Abiotic examples in an aquatic ecosystem include water salinity, oxygen levels, pH levels, water menstruum rate, h2o depth and temperature.

At present, allow's take a look at the significant divergence between the abiotic and biotic factors.

Departure between Abiotic and Biotic Resource

Post-obit are the important difference between abiotic and biotic factors:

Difference Between Biotic Resource and Abiotic Resources
Biotic Resource	Abiotic Resources
Definition
Biotic factors include all the living components present in an ecosystem	Abiotic factors refer to all the non-living, i.e. physical conditions and chemical factors that influence an ecosystem
Examples
Examples of biotic resources include all flora and beast	Examples of abiotic factors include sunlight, water, air, humidity, pH, temperature, salinity,  precipitation, altitude, type of soil, minerals, air current, dissolved oxygen, mineral nutrients present in the soil, air and h2o, etc.
Dependence
Biotic factors depend on abiotic factors for survival and reproduction	Abiotic factors are completely independent of biotic factors
Origin
Biotic components originate from the biosphere	Abiotic components originate from the lithosphere, hydrosphere and atmosphere

Oft Asked Questions

1. What are biotic factors?

Biotic factors are the living components present in an ecosystem. More specifically, it includes all flora and fauna.

2. Country a few examples of biotic resources.

• Plants
• Animals
• Fungi
• Leaner

3. What are abiotic factors?

Abiotic factors refer to all the not-living components present in an ecosystem. It typically comprises physical and chemical components.

iv. Country a few examples of abiotic factors.

Abiotic factors comprise the following:

• Climate
• Humidity
• Precipitation
• Current of air
• Distance
• Type of soil
• Low-cal penetration
• Water depth
• Oxygen content
• Turbidity

five. Elaborate an example of the interaction betwixt abiotic and biotic resource.

Biotic resources include every lifeform in an ecosystem. These lifeforms rely on abiotic factors equally they directly affect their growth, survival and reproduction. For example, turbidity is an abiotic factor that majorly affects the aquatic ecosystem. High levels of turbidity inhibit the growth of submerged plants. This consequently affects other species which depend upon these plants for food or shelter.
