Science - habitats

• A habitat is the place where an organism lives.
• The biome is a large natural community of flora and fauna occupying a major habitat
• An ecosystem is all living things (biotic) and non-living things (abiotic) that interact with one another within a specific area.
• The biome is a large natural community of plants and animals occupying a major habitat
• Ecosystems can be classified into terrestrial (land based), aquatic (water based) and marine (ocean based).
• Biotic factors are living components of an environment, such as plants or animals.
• Abiotic factors are physical features of an environment, such as temperature, water availability, soil type, light intensity, etc.
• Ecosystems are made up of communities, which are groups of different species living together in the same area.
• Communities can be found in many places such as forests, deserts or oceans.
• Each community has its own set of abiotic factors like temperature, light intensity, water availability etc.
• Terrestrial ecosystems are found on land, such as forests or grasslands.
• Aquatic ecosystems are found in water bodies like rivers, lakes, ponds, oceans etc.
• Marine ecosystems are found in the ocean.
• Terrestrial ecosystems include forests, grasslands, deserts, tundras, wetlands, and mountains.
• Terrestrial ecosystems include forests, grasslands, deserts, tundras, and wetlands.
• Forests cover about 30% of Earth's land surface and contain over two thirds of its plant species.
• Forests have trees as the dominant vegetation and support many different species of plants and animals.
• Species are groups of similar organisms capable of interbreeding and producing fertile offspring.
• Populations consist of organisms belonging to the same species living in the same place at the same time.
• Each ecosystem has its own unique set of abiotic and biotic factors that determine what organisms live there.
• Grasslands have low precipitation levels but high temperatures, with tall grasses growing to protect from wind erosion.
• Examples of ecosystems include coral reefs, rainforests, grasslands, tundras, freshwater lakes, salt marshes, and deserts.
• Freshwater ecosystems are found in bodies of freshwater, such as rivers or lakes.
• The food chain is a sequence of organisms that eat other organisms to get energy.
• Biomes include tundra, taiga, temperate deciduous forest, tropical rainforest, desert, chaparral, grassland, savanna, temperate grassland, Mediterranean climate, temperate coniferous forest, boreal forest, aquatic biomes (freshwater and marine)
• Grasslands have plants with long stems and leaves adapted to survive drought conditions.
• Forests have trees that grow tall and close together to form a canopy layer.
• Grasslands have plants with long stems and leaves adapted to survive drought conditions.
• Deserts receive very little rainfall and have sparse vegetation.
• Grasslands have plants with long roots that reach deep into the soil to find water during dry seasons.
• Deserts receive very little rainfall and have few plants adapted to survive in arid conditions.
• Desert ecosystems receive less than 25 cm (10 inches) of precipitation per year and can be hot during the day but cold at night.
• The Arctic is an area that surrounds the North Pole and has very little sunlight during winter months.
• Temperate forests receive moderate rainfall and have deciduous trees that lose their leaves during winter.
• Producers make their own food using sunlight, water, carbon dioxide, and minerals.
• Consumers obtain energy by eating producers or other consumers.
• Decomposers break down dead organic matter into simpler substances.
• Temperate Grasslands have large herbivores like bison and prairie dogs.
• Savannas have scattered trees and grasses.
• Rainforest trees grow tall to compete for light and have large leaves to absorb more sunlight.
