Ecology Practical Activities - KCSE Biology Notes

7/6/2021

0 Comments

 

Ecology Practical Activities

  • Ecology is best studied outdoors. Students identify a habitat within or near the school compound, e.g. a flower bed.
  • The quadrat method is used.
  • Observation and recording of the various animals as well as their feeding habits is done.
  • Birds that feed on the plants or arthropods in the area studied are noted through observation of habitat at various times of the day.
  • Food chains are constructed e.g. green plants ~ caterpillar ~ lizard and many others involving all organisms in the area. 
ECOLOGY PRACTICAL ACTIVITIES
  • The numbers of animals in 1M squared  is counted directly or estimated e.g. small arthropods like black ants.
  • The number of plants is easily counted and recorded and ratio of consumers to producers calculated.
  • It will be noted that in terms of numbers where invertebrates are involved, there are very many consumers of one plant.
  • Several other quadrats are established and studied and averages calculated.

Adaptions to Habitat

Hydrophytes
  • Specimen of hydrophytes e.g. water lily is observed.
  • Students should note the poorly developed root systems and broad leaves.
  • Stomata distribution on leaf surface is studied through microscopy or by immersing a leaf in hot water and counting number of bubbles evolved. 
Mesophytes
  • Ordinary plants e.g bean hibiscus and zebrina can be studied.
  • Size of leaves is noted and stomata distribution studied.
Xerophytes
  • Specimen include Euphorbia, cactus and sisal which are easily available.
  • The root system e.g. in sisal is noted as shallow but extensive.
  • It will be noted that sisal has fleshy leaves and stem while cactus and Euphorbia have fleshy stem but leaves are reduced to small hair-like structures.

​Comparison of Root nodules from fertile and poor soils 

Root nodules
  • These are swellings on roots of leguminous plants.
  • Soil fertility determines number of root nodules per plant.
  • Bean plants are best used in this study.
  • One plot can be manured while the other is not.
  • Similar seeds are planted in the two plots.
  • The plants are uprooted when fully mature (vegetatively) i.e. any time after flowering and before drying.
  • The number of nodules per plant is counted.
  • An average for each plot is calculated.
  • It is noted that the beans from fertile soil have more and large nodules than those grown in poor soils. 

​Estimation of Population using Sampling Methods 

  • The number of organisms both producers and the various consumers is recorded in each area studied e.g. using a quadrat.
  • The total area of the habitat studied is measured.
  • The average number of organisms per quadrat (1 m2) is calculated after establishing as many quadrats as are necessary to cover the area adequately.
  • Total population of organisms is calculated from the area.
  • Abiotic environment is studied within the area sampled.
  • Air temperature soil surface temperature are taken and recorded.
  • This is best done at different times of day, i.e., morning afternoon and evening.
  • Any variations are noted.
  • pH of the soil is measured using pH distilled water to make a solution.
  • Litmus papers can be used to indicate if soil is acidic or alkaline, but pH paper or meter gives more precise pH values.
  • Humidity is measured using anhydrous blue cobalt chloride paper which gives a mere indication of level of humidity.
  • A windsock is used to give an indication of direction of wind.
  • As all the abiotic factors are recorded observations are made to find the relationships between behaviour of organism and the environmental factors for example:
    • The temperature affects the behaviour of animals.
    • The direction of wind will affect growth of plants.
    • The level of humidity determines the type, number and distribution of organisms in an area.
