Study Notes
Ecosystem Classification
- Ecosystems are classified based on their origin as natural and artificial.
- Natural ecosystems are those that develop naturally without human intervention.
- Artificial ecosystems are those that are created and managed by humans.
Ecosystem Structure
- Biotic components involve the continuous interaction resulting in a characteristic physical structure.
- The structure of an ecosystem involves both biotic and abiotic components.
- The biotic components include all living organisms within the ecosystem.
- The abiotic components include the physical and chemical factors that influence the ecosystem.
- The vertical distribution of different species occupying different levels in an ecosystem is known as stratification.
Ecosystem Energy Flow
- The continuous input of energy from an ultimate source, mainly the Sun, is tapped by producers.
- Producers are organisms that can convert sunlight into chemical energy.
- Consumers are organisms that obtain their energy by eating other organisms.
- Decomposers are organisms that break down dead organic matter.
Natural Ecosystem Classification
- Terrestrial ecosystems are land-based ecosystems, such as forests, grasslands, and deserts.
- Aquatic ecosystems are water-based ecosystems, such as lakes, rivers, and oceans.
Decomposers and Detritus
- Decomposers play a crucial role in recycling nutrients back into the ecosystem.
- Detritus usually comprises dead organic matter, such as leaves, branches, and animal carcasses.
- The rate of decomposition is affected by several factors, including temperature, moisture, and the availability of nutrients.
Ecosystem Productivity
- Primary productivity in an ecosystem is defined as the rate at which organic matter is produced by producers.
- Gross primary productivity is the total amount of organic matter produced by producers.
- Net primary productivity is the amount of organic matter produced by producers after subtracting the amount they use for respiration.
- Secondary productivity is the rate at which consumers convert food into new biomass.
Autotrophs and Ecosystem Components
- Autotrophs, also known as producers, can synthesize their own food from inorganic substances.
- The two primary parts of an ecosystem are the biotic community and the abiotic environment.
- Energy in ecosystems comes from the sun.
Niche in Ecosystems
- A niche in an ecosystem refers to the role or functional position of a species within an ecosystem.
Threats to Ecosystems
- Habitat loss, pollution, and climate change are some significant threats to ecosystems.
Habitat in Ecosystems
- Habitat refers to the place or environment where an organism lives.
Energy Flow in Ecosystems
- Energy moves through an ecosystem in a one-way flow, from producers to consumers and then to decomposers.
- Energy is lost at each trophic level as it is used for metabolic processes.
