The interaction of living organisms with each other and with their environment is:
Ecology is the study of the interactions of living organisms with each other and with their environment.
A place of living according to a particular environment of a living thing is:
A habitat is a specific place or environment where an organism naturally lives and grows.
Area where river meets with sea is:
An estuary is where a river meets the sea, mixing freshwater with saltwater.
Area below the ice cap has a very cold climate:
The tundra is characterized by extremely cold temperatures and is located in the Arctic regions.
The food chain always starts from:
A food chain always starts with a producer, which is typically a green plant or another photosynthetic organism.
Interaction between living and non-living things in a place is called?
An ecosystem consists of all the living organisms and non-living components interacting in a specific area.
Which of the following is a biotic factor?
Biotic factors are living components of the environment, such as animals.
Which factor is not an abiotic factor?
Biotic factors are living components, and a bird is a living organism.
What are green plants called in a food chain?
Green plants are called producers because they produce their own food through photosynthesis.
Why are green plants called producers?
Green plants are called producers because they make their own food using sunlight through the process of photosynthesis.
Who are consumers in a food chain?
Consumers are organisms that eat other organisms, such as animals that eat plants or other animals.
What is the food chain?
A food chain describes the feeding relationships between organisms in an ecosystem, showing who eats whom.
What does a food chain always begin with?
A food chain always begins with a producer, which is typically a plant or other photosynthetic organism.
What forms when many food chains are connected?
When many food chains are connected, they form a food web, which represents the complex network of feeding relationships in an ecosystem.
The non-living parts of an ecosystem are known as:
Abiotic components are the non-living parts of an ecosystem, such as soil, water, and air.
Producers in an ecosystem are usually:
Producers in an ecosystem are usually plants, which produce their own food through photosynthesis.
Which of the following is an abiotic factor?
Soil is an abiotic factor because it is a non-living component of the ecosystem.
Which component breaks down dead organisms and recycles nutrients?
Decomposers break down dead organisms and recycle nutrients back into the ecosystem.
Which of these is an example of a freshwater ecosystem?
A pond is an example of a freshwater ecosystem, characterized by low salt concentration.
In a food chain, which organisms feed directly on plants?
Primary consumers feed directly on plants, making them herbivores in the food chain.
Which of these is a terrestrial ecosystem?
Grassland is a terrestrial ecosystem, characterized by land-based habitats with grasses as the dominant vegetation.
Which organisms get energy from dead and decaying matter?
Decomposers get energy from dead and decaying matter by breaking it down and recycling nutrients.
What are the two main types of habitats?
The two main types of habitats are aquatic (water-based) and terrestrial (land-based).
Which habitat has salty water?
The sea is a habitat with salty water, known as a marine ecosystem.
What type of water is found in freshwater habitats?
Freshwater habitats are characterized by water with low salt concentration.
Where do rivers and streams belong?
Rivers and streams belong to aquatic habitats, as they are bodies of water.
Which plant grows near coastal areas?
Palm trees often grow near coastal areas due to their adaptation to sandy soil and salty environments.
Which animal lives in cold areas and has thick fur?
Polar bears live in cold areas and have thick fur to insulate against the cold climate.
Why do humans living in warm areas have darker skin?
Darker skin provides protection against the harmful effects of sunlight, particularly UV radiation.
What is the purpose of broad leaves in some plants?
Broad leaves help plants absorb more sunlight, which is essential for photosynthesis.
What adaptation helps cactus survive in dry areas?
Cacti have spines instead of leaves to reduce water loss and protect against herbivores.
Which animal stores water in its body to survive in deserts?
Camels store water in their bodies, allowing them to survive in desert environments.
What helps animals survive cold temperatures?
Thick fur helps animals survive cold temperatures by providing insulation and retaining body heat.
What are animals active at night called?
Nocturnal animals are active at night, which is an adaptation to avoid predators or extreme daytime heat.
Which one is a diurnal animal?
A sparrow is a diurnal animal, meaning it is active during the day.
What can cause fire in forests?
Lightning can cause fires in forests by igniting dry vegetation.
Which animal activity involves sleeping through winter to save energy?
Hibernation is an animal activity that involves sleeping through winter to conserve energy.
What is estivation?
Estivation is a state of dormancy that some animals enter during hot and dry periods to conserve energy and survive.
Which animals have scales as body covering?
Fish and reptiles have scales as a form of body covering, which provides protection.
Which physical factor directly affects photosynthesis in plants?
Light intensity directly affects photosynthesis in plants, as light is essential for the process.
What does a food chain always start with?
A food chain always starts with a producer, which is typically a plant or another photosynthetic organism.
What are herbivores also called in a food chain?
Herbivores are also called primary consumers in a food chain because they feed directly on producers.
Who eats the primary consumers in a food chain?
Secondary consumers eat primary consumers in a food chain, making them typically carnivores or omnivores.
Which of the following is a decomposer?
Fungi are decomposers that break down dead organic matter and recycle nutrients.
What is the correct order of a simple forest food chain?
The correct order of a simple forest food chain is: Grass (Producer) → Grasshopper (Primary Consumer) → Lizard (Secondary Consumer) → Hawk (Tertiary Consumer).
Which animal can be both a primary and secondary consumer?
A mouse can be both a primary consumer (when eating plants) and a secondary consumer (when eating insects).
What type of consumer is a hawk in a food chain?
A hawk is typically a tertiary consumer in a food chain, feeding on secondary consumers.
