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.
Tiwari Academy Discussion Latest Questions
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.
Adaptations enhance survival by allowing organisms to better fit their environment. They improve an organism’s ability to obtain resources, avoid predators, and cope with environmental stresses, increasing their chances of survival and reproduction.
Key characteristics of living organisms include cellular organization, metabolism, growth, reproduction, response to stimuli, and homeostasis. Non-living things lack these processes and functions that are essential for life.
The environment influences the survival of living creatures by providing essential resources like food, water, and shelter, and by presenting challenges such as predators and climate. Adaptations to these factors are crucial for survival.
