Study Notes

சுற்றாடல் (Ecosystem)

Food Chain

A food chain is a series of organisms that eat other organisms, with each level representing a trophic level.

Components of a Food Chain:

Producers: Autotrophic organisms like plants, phytoplankton, and algae that produce their own food through photosynthesis.
Primary Consumers: Herbivores that feed on producers, such as insects, rodents, and deer.
Secondary Consumers: Carnivores that feed on primary consumers, such as frogs, snakes, and birds of prey.
Tertiary Consumers: Apex predators that feed on secondary consumers, such as sharks, lions, and top predators.
Decomposers: Organisms like bacteria and fungi that break down dead organic matter.

Characteristics of a Food Chain:

Energy is transferred from one trophic level to the next, with some energy lost as heat at each level.
Each trophic level has a specific role and is dependent on the previous level.
Food chains are interconnected and form a complex network.

Types of Food Chains:

Grassland Food Chain: Producers → Herbivores → Carnivores → Apex Predators
Aquatic Food Chain: Phytoplankton → Zooplankton → Fish → Top Predators
Forest Food Chain: Trees → Insects → Small Mammals → Large Predators

Definition of Biodiversity

Biodiversity refers to the variety of different species of plants, animals, and microorganisms that live in an ecosystem or on Earth as a whole.
It also includes genetic diversity within each species, variety of ecosystems, and interactions between different species and their environment.

Types of Biodiversity

Species diversity: Number of different species present in an ecosystem.
Genetic diversity: Variety of genes within a species or population.
Ecosystem diversity: Variety of different ecosystems present in an area, such as forests, grasslands, and deserts.

Importance of Biodiversity

Ecosystem services: Biodiversity provides essential services like air and water purification, soil formation, and climate regulation.
Food security: Many crops and livestock rely on biodiversity to pollinate, control pests, and maintain soil health.
Medicine: Biodiversity is a source of new medicines and treatments for human diseases.

Threats to Biodiversity

Habitat destruction: Human activities like deforestation, land conversion, and pollution lead to habitat loss and fragmentation.
Climate change: Rising temperatures and changing weather patterns affect the distribution and extinction of species.
Overexploitation: Overhunting, overfishing, and unsustainable harvesting of resources threaten biodiversity.

Conservation of Biodiversity

Protected areas: National parks, wildlife reserves, and other protected areas help preserve habitats and ecosystems.
Sustainable practices: Sustainable agriculture, forestry, and fishing reduce the impact of human activities on biodiversity.
Education and awareness: Raising awareness about the importance of biodiversity and the threats it faces inspires individual and collective action to conserve it.
