What is an ecosystem?
An ecosystem is a community of living organisms and their interactions with the non-living components in their environment.
What are the two main components of an ecosystem?
The two main components of an ecosystem are the biotic (living) and abiotic (non-living) factors.
Give an example of a terrestrial ecosystem.
An example of a terrestrial ecosystem is a forest.
What is the role of producers in an ecosystem?
Producers, such as plants, convert sunlight into energy through photosynthesis.
Define the term 'food chain'.
A food chain represents the transfer of energy from one organism to another in an ecosystem.
What is the primary source of energy in most ecosystems?
The sun is the primary source of energy in most ecosystems.
How does a predator-prey relationship impact an ecosystem?
A predator-prey relationship helps maintain balance in an ecosystem by controlling population sizes.
What is a decomposer and give an example.
A decomposer is an organism that breaks down dead organic matter. An example is fungi.
Explain the concept of biodiversity in an ecosystem.
Biodiversity refers to the variety of species and ecosystems present in a given area.
What is the difference between a food chain and a food web?
A food chain is a linear sequence of organisms, while a food web is a more complex network of interconnected food chains.
What is an ecological niche?
An ecological niche refers to the role and position of a species within its environment.
What are some examples of abiotic factors in an aquatic ecosystem?
Examples of abiotic factors in an aquatic ecosystem include water temperature, pH level, and dissolved oxygen.
How does human activity impact ecosystems?
Human activity can lead to habitat destruction, pollution, and the introduction of invasive species, negatively impacting ecosystems.
What are the three main types of ecological pyramids?
The three main types of ecological pyramids are pyramid of numbers, pyramid of biomass, and pyramid of energy.
What is the importance of conservation in maintaining healthy ecosystems?
Conservation helps protect and preserve biodiversity, habitats, and the overall balance of ecosystems.
What are the major threats to global ecosystems?
Major threats to global ecosystems include climate change, deforestation, pollution, and overexploitation of resources.
