V. Ecology and environment (Periods 12)

a.  Organisms  and  environment:  Habitat  and  niche;  Population  and ecological  adaptations; population  interactions-mutualism,  competition, predation, parasitism; Population attributes-growth, birth rate and death rate, age distribution.

b. Ecosystems: Patterns, components;  productivity and  decomposition; Energy  flow; Pyramids of number, biomass, energy; Nutrient cycling (carbon and phosphorous); Ecological succession; Ecological Services- Carbon fixation; pollination, oxygen release.

c. Biodiversity and its conservation: Concept of Biodiversity; Patterns of Biodiversity; Importance of Biodiversity; Loss of Biodiversity, conservation; Hotspots, endangered organisms,  extinction, Red  Data  Book:  Biosphere  reserves,  National  parks  and Sanctuaries.

d. Environmental issues:  Air pollution and its control;  Water pollution and its control; agrochemicals  and  their  effects;  Solid  waste  management;  Radioactive  waste management; Greenhouse effect and global warming; Ozone depletion; Deforestation; Any three case studies as success stories addressing environmental issues.

Chapter-13: Organisms and Populations

Organisms  and  environment:  Habitat  and  niche,  abiotic  factors,  ecological  adaptations;  population  interactions  -  mutualism,  competition,  predation,  parasitism,  commensalism; population attributes - growth, birth rate and death rate, age distribution.

Chapter-14: Ecosystem

Ecosystem:  structure and  function;  productivity and decomposition; energy flow; pyramids of number,  biomass,  energy;  nutrient  cycles  (carbon  and  phosphorous);  ecological  succession; ecological services - carbon fixation, pollination, seed dispersal, oxygen release (in brief).

Chapter-15: Biodiversity and Conservation

Biodiversity  -  Concept,  levels,  patterns,  importance;  loss  of  biodiversity;  biodiversity conservation;  hotspots,  endangered  organisms,  extinction,  Red  Data  Book,  Sacred  Groves, biosphere reserves, national parks, wildlife, sanctuaries and Ramsar sites. 

Chapter-16: Environmental Issues

Air pollution and its  control; water pollution and its control; agrochemicals and their effects; solid waste management; radioactive waste management; greenhouse effect and climate change impact  and  mitigation;  ozone  layer  depletion;  deforestation;  case  study  exemplifying  success story addressing environmental issue(s).
