Memorandum

1. Number of plant types: four

  • Four types: Trees: grow tall (long stem/trunk), branched, many leaves, standing singly.
  • Shrubs: like trees but not as high (stems not long)
  • Climbers/creepers: grow high but do not stand on their own – creeps or climbs up trees or any kind of structure.
  • Ground covers, herbs: low-growing

2. In trees/shrubs: Insects, birds, snakes, squirrels

  • On the ground: Mice, insects, rabbits, birds, snakes, frogs
  • In ground litter: Earthworms and other worms/caterpillars cicadas, frogs
  • In soil: Earthworms, moles, snakes
  • In water: Fish, insects, frogs

3. Each plant and animal is adapted for survival in its environment in a particular manner.

Activity 2: to interpret information gathered in a study of an ecosystem [lo 2.3]

Variety (diversity) within an ecosystem

An ecosystem is characterised by a large variety of living organisms.

Look at the accompanying illustration of an ecosystem and answer the questions that follow. If you have access to a place where plants grow, especially if there also is water such as a stream or a dam, it could be worthwhile to spend a bit of time there and to try to find further information for your answers. You then have an ecosystem in which you can make your observations.

  1. How many different types of plants can you distinguish? ________________
  • Try to distinguish four types and describe each of them:

2. Try to determine what types of animals you possibly might find in the following places in the ecosystem (consult books or investigate the ecosystem that you have chosen):

  • In the trees and shrubs above the soil:

__________________________________________________________________

__________________________________________________________________

__________________________________________________________________

  • On top of the soil:

__________________________________________________________________

__________________________________________________________________

__________________________________________________________________

  • In the layer of dead plant material on top of the soil:

__________________________________________________________________

__________________________________________________________________

__________________________________________________________________

  • In the soil:

__________________________________________________________________

__________________________________________________________________

__________________________________________________________________

  • In the water:

__________________________________________________________________

__________________________________________________________________

__________________________________________________________________

  • Why is there such a variety of plants and animals?

Assessment

Learning Outcome 2: The learner will know and be able to interpret and apply scientific, technological and environmental knowledge.

Assessment Standard 2.3: We know this when the learner interprets information.

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct

is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
