Some of the
main topics for Biology chapter Organisms and Populations (Class 12) along with
their details are:
1. Organisms and Their Environment -
This topic describes the relationships between organisms and their environment,
and how they adapt to their surroundings. It covers topics such as biotic and
abiotic factors, ecosystem, niche, habitat, and ecological succession.
2. Population and Its Dynamics -
This topic covers the characteristics of populations, such as size, density,
dispersion, and age structure. It also describes the factors that affect
population growth and regulation, such as birth rates, death rates,
immigration, emigration, and carrying capacity.
3. Diversity in Living Organisms -
This topic describes the different levels of classification for living
organisms, including Kingdom, Phylum, Class, Order, Family, Genus, and Species.
It also covers the characteristics and examples of different kingdoms, such as
Monera, Protista, Fungi, Plantae, and Animalia.
4. Biodiversity and Its Conservation
- This topic covers the importance of biodiversity in different ecosystems, the
threats to biodiversity, and the efforts to conserve it. It includes topics
such as endangered and extinct species, habitat destruction, pollution, and
conservation strategies.
5. Ecosystems and Their Functioning
- This topic describes the structure and functions of different ecosystems,
such as forest, grassland, desert, wetland, and marine. It covers topics such
as food chains and webs, energy flow, nutrient cycling, and the roles of
different organisms in the ecosystem.
Overall, this chapter provides a
comprehensive discussion of the interactions between organisms and their
environment, the characteristics and dynamics of populations, the diversity of
living organisms, and the importance of biodiversity and ecosystem
conservation.
