LESSON ABOUT BIODIVERSITY AND EVOLUTION

1. JAYAR S. DEFEO

2. EVOLUTION
is the change in the
characteristics of a species over
several generations and relies
on the process of natural
selection.

21. Local and Global Environmental
Issues and Problems

22. A. Deforestation

23. EXTINCTION
is the displacement of the upper layer of
soil, it is one form of soil degradation.
This natural process is caused by the
dynamic activity of erosive agents, that
is, water, ice, snow, air, plants, animals,
and humans.

24. B. WILDLIFE DEPLETION
Extinct animals in the Philippines

25. Endangered animals in the Philippines

26. C. Water Pollution

29. D. Air Pollution

30. D. Air Pollution

31. E. Destruction of Coastal Resources

32. F. Acid Precipitation

33. Activity
1. Is the contamination of water bodies (e.g. lakes, rivers, oceans, aquifers and
groundwater).
2. A group of living organism of the same species living in a certain place.
3. A group of organism that have certain characteristics in common and are able to
interbreed.
4. Occurs when the last member of the species dies.
5. Variety of life in an area.
6. It is the displacement of the upper layer of soil, it is one form of soil degradation.
7. Removing or clearing of a forest that includes cutting of all trees.
8. Tiny particles of soot, dust and smoke.
9. Occurs when the population has become so low that it is possible of becoming
extinct.
10.Anything that limits the size of a population like certain environmental conditions
are called

34. 1-6. Enumerate the different
Environmental Issues and
Problems
7-9. Causes of Deforestation
10-11. Example of Extinct Animals
12-15. Example of Endangered
Animals

35. 1. Suppose 125 ants live in a 8 sq.m plot
of grass. What would be the population
density of the ants?
2. If 65 carabaos live in a 2.5 sq.m
area, what is their population
density?
