To decide which stage follows the egg, observe the life cycle of the specific insect. For many insects, the larva stage comes immediately after the egg, while the pupa stage follows the larva.
Both mosquitoes and frogs have aquatic larval stages. Mosquitoes transition from eggs to larvae to pupae before becoming adults, while frogs start as eggs, hatch into tadpoles, and then undergo metamorphosis into frogs.
The Western Ghats is a biodiversity hotspot that supports a wide variety of plants and animals. It plays a vital role in regulating the climate, controlling rainfall patterns, and providing habitat for many species, making it crucial for the environment.
Soil forms through the weathering of rocks and organic matter decomposition. Over time, physical and chemical processes break down rocks, and living organisms contribute organic material, creating the layers and nutrients essential for fertile soil.
Cutting a large forest area leads to habitat loss, soil erosion, reduced biodiversity, and increased carbon dioxide levels. It disrupts ecosystems, contributes to climate change, and diminishes the natural resources and services forests provide.
Seasons on Earth are caused by its tilt on its axis and its orbit around the Sun. This tilt leads to varying angles of sunlight and day lengths throughout the year, creating different seasons.
Gravity is the force that governs the movement of celestial bodies in the solar system. It keeps planets in orbit around the Sun and influences the paths of moons, comets, and asteroids.
Planets and stars can be distinguished by their appearance. Planets usually shine with a steady light and move against the background of fixed stars. Stars twinkle due to atmospheric disturbances, while planets do not.
The shell is significant in a snail’s life cycle as it provides protection and support throughout its development. It also helps in regulating moisture levels and serves as a retreat during vulnerable stages.
