The following is an example of an abiotic part of an ecosystem:
Abiotic components are non-living chemical and physical parts of the environment that affect living organisms. Minerals are non-living and thus an abiotic component.
The following is an example of a biotic component of an environment:
Biotic components are living organisms in an ecosystem. Bacteria are living organisms and thus a biotic component.
Tapeworms that live inside organisms and feed on the nutrients of the food organism eat, are an example of:
Parasitism is a relationship where one organism, the parasite, lives on or in another organism, the host, causing harm to the host.
Organisms in an ecosystem can be classified as producers or consumers. The producers provide food for the consumers. Name the organism that consumes both producers and other consumers:
Omnivores are organisms that eat both plants (producers) and meat (other consumers).
Carbon is an integral part of an ecosystem. It is cycled throughout the ecosystem as it is used and then reused. It is necessary for all life to exist. Name the process in which plants use carbon dioxide:
Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of carbon dioxide and water.
Photosynthesis is a chemical reaction that occurs in the leaves of plants. But it requires a special gas, an abiotic component from the atmosphere. What is this substance?
Carbon dioxide is a crucial gas required for photosynthesis, where plants convert light energy into chemical energy.
Which of the following are known as producers in an ecosystem?
Producers are organisms that can produce their own food through photosynthesis, such as green plants and algae.
Animals that eat only plants are called:
Primary consumers are herbivores that feed on producers (plants).
Which of the following is a secondary consumer?
Secondary consumers are typically carnivores that eat primary consumers. Lions are carnivores that feed on herbivores.
What role do decomposers play in nature?
Decomposers break down dead organic material, returning vital nutrients to the ecosystem.
Which of these organisms is a decomposer?
Bacteria are decomposers that break down dead material and recycle nutrients.
What is the main source of energy for producers?
Producers, such as plants, use sunlight to produce food through the process of photosynthesis.
During photosynthesis, plants use sunlight, carbon dioxide, and __________:
In photosynthesis, plants use water along with sunlight and carbon dioxide to produce glucose and oxygen.
Which of the following is not an abiotic factor?
Abiotic factors are non-living components of the environment, whereas a bird is a living organism.
Which environment is known to support over half of the world's species?
Rainforests are known for their biodiversity, supporting a vast number of species.
What do we call the study of relationships between living and nonliving components of the environment?
Ecology is the study of interactions among organisms and their environment.
Which of the following is an abiotic component of the ecosystem?
Water is a non-living component, making it an abiotic factor in ecosystems.
Which of the following is a producer in a grassland ecosystem?
Grass is a producer because it can perform photosynthesis to create its own food.
What role do decomposers play in an ecosystem?
Decomposers break down dead organisms, recycling nutrients back into the ecosystem.
Which of the following is an example of a decomposer?
Bacteria are decomposers that play a crucial role in breaking down dead organic matter.
How do consumers obtain their energy?
Consumers obtain energy by eating other organisms, as they cannot produce their own food.
Which of the following best describes an ecosystem?
An ecosystem consists of interactions between living organisms and their nonliving environment.
What is the main energy source for producers?
Producers use solar energy to perform photosynthesis and produce food.
Which component is NOT biotic?
Minerals are non-living and thus not a biotic component of the ecosystem.
Which phenomenon can lead to fish population destruction?
Acid rain can lower the pH of water bodies, making them uninhabitable for fish.
Which of the following is an example of a limiting factor for plant growth in a desert?
In deserts, the lack of water is a significant limiting factor for plant growth.
How does carbon dioxide help plants?
Carbon dioxide is essential for photosynthesis, the process by which plants produce food.
What type of relationship exists when one organism hunts and eats another?
The predator-prey relationship involves one organism hunting and consuming another for food.
In a predator-prey interaction, who is harmed?
In a predator-prey interaction, the prey is harmed as it is consumed by the predator.
Which of the following best describes parasitism?
Parasitism is a relationship where one organism benefits at the expense of the other, which is harmed.
Which of these is an example of parasitism?
A mosquito sucking blood is an example of parasitism as the mosquito benefits while the host is harmed.
What is mutualism?
Mutualism is a type of symbiotic relationship where both organisms involved benefit from the interaction.
Which of these shows mutualism in action?
The relationship between a honeybee and a flower is mutualistic as the bee gets nectar and the flower gets pollinated.
Which interaction involves direct feeding on another living organism?
The predator-prey interaction involves one organism feeding directly on another living organism.
In parasitism, what is the organism that gets harmed called?
In parasitism, the organism that is harmed is called the host.
Which relationship helps both organisms survive better in their environment?
Mutualism is a relationship where both organisms benefit, helping them survive better in their environment.
