ii. Plant
e. Make a list of environmental factors affecting animals and plants.
f. Mention the benefits of sunlight and soil to living things.
g. What does a plant need to make food?
h. Describe the interrelationship between the organism and the environment.
i. Write down how animals and plants can benefit from water.
Earthworms are very useful organisms for soil and plants. Justify this statement.
Answer (2)
An environment includes both living and non-living components that interact. Animals support plants through pollination and seed dispersal, while also benefiting humans and ecosystems. Earthworms enhance soil health, which promotes plant growth, showing the interconnected relationships in nature.

a. An environment is everything that surrounds us, including the air, water, soil, plants, and animals. It provides the necessary conditions for organisms to live and interact with each other.
b. Animals help plants in various ways, such as pollination, which is the process where animals like bees and butterflies transfer pollen from one flower to another, helping plants reproduce. Additionally, animals can aid in seed dispersal, helping plants spread their offspring by carrying seeds to new locations.
c. Animals provide numerous benefits to humans, including food (like meat, eggs, and dairy products), clothing (such as wool and leather), companionship, and service (like guide dogs). They also contribute to ecosystems by maintaining balance, such as controlling pest populations.
d. i. Bees help humans by pollinating crops, which increases agricultural yields and provides food. ii. Bees assist plants by aiding in their reproduction through pollination, which helps in seed and fruit production.
e. Environmental factors affecting animals and plants include climate (temperature, humidity, precipitation), sunlight, soil quality, water availability, and human activities (like pollution and deforestation).
f. Sunlight provides energy for photosynthesis, a process by which plants make food. Soil offers nutrients crucial for plant growth and serves as a habitat for various organisms.
g. Plants need sunlight, carbon dioxide, water, and nutrients from the soil to conduct photosynthesis and make food.
h. The interrelationship between organisms and the environment is a dynamic balance, where organisms depend on environmental conditions to survive, and in turn, they influence the environment. For example, plants use sunlight for photosynthesis, and animals rely on plants for food and oxygen. This balance is essential for maintaining ecosystems.
i. Animals and plants derive benefits from water by using it for hydration, photosynthesis, nutrient uptake (in plants), and habitat (like fish in water bodies).
Earthworms are useful organisms for soil and plants because they aerate the soil, enhancing its structure and nutrients, which helps plants grow better. Their tunneling improves water infiltration and root growth, making them important for maintaining healthy soil and ecosystems.
