Predation is an ecological interaction where one organism (predator) hunts and consumes another (prey) for energy and nutrients.
Carbon dioxide (CO₂) is the primary greenhouse gas responsible for global warming, accounting for about 75% of anthropogenic greenhouse gas emissions.
Solar energy is a renewable resource that can be naturally replenished. Coal, petroleum, and natural gas are non-renewable fossil fuels.
Deserts receive less than 25 cm (10 inches) of rainfall annually, making them the driest biomes on Earth.
Lichens are classic pioneer species in primary succession as they can colonize bare rock, secrete acids to break it down, and create conditions for soil formation.
Primary succession occurs on areas with no pre-existing soil, such as bare rock or new volcanic islands. Pioneer species like lichens initiate the process.
Only 1-5% of incident solar radiation is actually fixed by plants through photosynthesis. The rest is either reflected or absorbed as heat.
Solar radiation is the ultimate source of energy for all ecosystems. Plants capture this energy through photosynthesis, which forms the base of all food chains.
