It creates a functional unit of nature through interactions between organisms and their environment.
Natural ecosystems and artificial ecosystems.
Autotrophs produce their own food, while heterotrophs rely on others for food.
Energy flows unidirectionally from green plants to herbivores and then to carnivores.
Energy decreases at each trophic level due to loss as heat.
A food chain shows a linear flow, while a food web represents interconnected food chains.
It shows energy flow at each trophic level, always upright due to energy loss.
Producers create food from sunlight, while consumers depend on other organisms for food.
It starts with dead organic matter and flows through microorganisms to predators.
It is the increasing concentration of toxins in organisms at higher food chain levels.
It refers to the variation of genes within a species or population.
It includes the variety of habitats and ecological processes within ecosystems.
A region with significant biodiversity that is threatened by human activities.
Critically endangered species face an extremely high risk of extinction, while endangered species face a very high risk.
A protected area that preserves animals and plants from harm and promotes biodiversity.
To conserve Bengal tigers in their natural habitat and prevent their extinction.
Resources that can be regenerated or recycled within a short time frame.
They lack metallic properties but are essential for various industries.
Minerals that contain metals and are good conductors of heat and electricity.
Forest, water, mineral, land, food, and energy resources.
Into living (biotic) and non-living (abiotic) resources.
Minerals are classified as metallic, non-metallic, energy, and precious minerals.
It shows the total dry matter at each trophic level.
Forests have an upright pyramid; ponds have an inverted pyramid.
Only 10% of energy passes to the next trophic level.
They convert solar energy into food.
Consumers depend on other organisms for food.
Decomposers break down amino acids to produce ammonia.
They recycle nutrients back into the ecosystem.
It consists of interconnected food chains.
Grazing starts with living plants; detritus starts with dead organic matter.
It shows the interaction between grazing and detritus food chains.
The conversion of atmospheric nitrogen into usable forms.
They help legumes convert nitrogen into ammonia.
Ammonia is oxidized to nitrite and then to nitrate.
The process of converting nitrates back to gaseous nitrogen.
Energy cannot be created or destroyed, only transformed.
It dissipates and decreases at each level.
