Snails adapt to their environment through behavioral and physiological changes, such as seeking moist habitats to prevent dehydration and retracting into their shells for protection. These adaptations help them survive and thrive.
Feedback mechanisms are crucial for maintaining homeostasis in living organisms. They help regulate internal conditions by detecting changes and initiating responses to restore balance, ensuring the organism’s stability and survival.
Decomposers break down dead organisms and waste products, recycling nutrients back into the ecosystem. This process helps maintain soil fertility and supports the growth of plants, completing the nutrient cycle in ecosystems.
Organisms in an ecosystem interact through various relationships such as predation, competition, mutualism, and parasitism. These interactions affect their survival, reproduction, and the overall balance and health of the ecosystem.
Biodiversity enhances ecosystem stability, productivity, and resilience. It ensures a variety of species and genetic diversity, contributing to ecosystem services, adaptation to environmental changes, and overall health of the environment.
Enzymes are biological catalysts that speed up biochemical reactions by lowering activation energy. They bind to substrates, facilitate the conversion into products, and are then released to catalyze additional reactions.
Photosynthesis allows plants and some microorganisms to convert sunlight, carbon dioxide, and water into glucose and oxygen. This process provides the primary energy source for these organisms and produces oxygen essential for aerobic life.
Factors influencing photosynthesis include light intensity, carbon dioxide concentration, water availability, and temperature. Optimal levels of these factors increase the rate of photosynthesis, while deviations can limit or inhibit the process.
Cellular respiration converts glucose and oxygen into energy, carbon dioxide, and water. This process provides the energy required for various cellular activities, including growth, repair, and maintenance, crucial for sustaining life.
