- The abiotic components of an ecosystem include non-living things like soil, air, water, and light.
- The term 'ecosystem' comes from the Greek word 'oikos,' meaning 'house.'
- Forests, ponds, and grasslands are all examples of ecosystems.
- Sunlight is essential for all living organisms.
- Green plants use sunlight to photosynthesize.
- Animals either directly or indirectly rely on plants for food.
- Water is an essential component of all living organisms and makes up approximately 60% of the human body.
- Water is absorbed by plants through their roots.
- Water acts as a medium for transport in the bodies of both plants and animals.
- Temperature is a measure of warmth or coldness and is influenced by the sun's heat.
- The Earth's temperature supports the growth and survival of living organisms.
- The temperate deciduous forest has four distinct seasons – winter, spring, summer, and autumn.
- Boreal forests, also known as taiga, are characterized by coniferous trees like pines, spruces, and larches.
- Boreal forests have cold winters and warm summers and are often found near permanently frozen soil layers called permafrost.
- Drainage is poor in boreal forests due to layers of rocks and permafrost.
- The soil in boreal forests is acidic, mineral-poor and covered by a deep layer of rainfall.
