Biology- e-learning portal --Ecology, habitats & evolution

Hi Students,

Here is the sixth list of sites you can go to to learn science in a fun way.
The site is good for quick revisions and introductions to the topics.

Molecular Genetics, cell divisions, ecology, selection

Hi Students,

Below are a few links I found very useful in understanding concepts in Molecular Biology and genetics. Difficult concepts in cell division are also dealt with.

Ecology, bioaccumulation and bio-magnification are also dealt with in the powerpoints slideshows listed below.

I will go through these slideshows in class. You may want to browse through them for better understanding.

Lesson 37: Ecology, food chains and populations

Hi,

Everybody enjoys ecology and food chain studies. Here is more for your enjoyment.

This set of powerpoint slides contain the following which are relevant to your biology syllabus:

• energy flow, sunlight energy being converted to chemical energy by photosynthesis

• autotrophs(producers), heterotrophs(consumers), decomposers(soil bacteria and soil fungi)

• food chain (flow of energy through organisms)

• food web, examples of food webs

• pyramids of numbers, biomass, and energy

• carbon cycle

• quiz.

You can ignore the nitrogen and other mineral cycles as well as population studies as they are not in the biology syllabus for this year.

Lesson 15: Energy flows

Hi,

These slides cover an important part of express classes' syllabus. The coverage includes:

• flow of energy and minerals through the environment
• producers carry out photosynthesis to convert light energy into chemical energy
• glucose is sunlight energy in the form of a molecule
• primary consumers in a food chain, examples
• secondary consumers in a food chain, examples
  
• biomass, respiration, wastes
• energy efficiencies of consumers
• trophic levels
• decomposers, examples, functions in recycling minerals
• examples of food webs -marine, woodlands
• loss of biomass in food chains due to respiration and wastes
• pyramid of biomass
• pyramid of energy
• pyramid of numbers
• pesticides, toxic chemicals, bio-accumulations
  
• predator-prey cycles
• carbon cycle
• carbon dioxide and greenhouse effect
• effects of global warming
• very good short questions on topic
