interact with the environment
A. Biodiversity
B. Ecosystem

D. Species Diversity
E. Ecosystem Diversity
2. The variety of life forms in an ecosystem
3. Refers to all the different habitats, biological
communities,
and ecological processes, as well as variation
within individual ecosystems.
4- Refers to the variation of genes within the
species.
5. refers to the number of different species
present in a specific
location and the relative proportions of the
species present.

6. Team 3: Construct a sentence to define biodiversity based on
the words listed below (Pick at least 4)

8. Mufasa:
◦Everything you see exists together
in a delicate balance. As king, you
need to understand that balance
and respect all the creatures, from
the crawling ant to the leaping
antelope.

9. Simba:
◦But, Dad, don't
we eat the
antelope?

10. Mufasa:
◦Yes, Simba, but let me explain.
When we die, our bodies
become the grass, and the
antelope eat the grass. And so
we are all connected in the
great Circle of Life.

13. ◦What if one organism
vanishes?

OUTPUTS

20. ◦How can we see genetic
diversity in us humans?

27. ◦A more diverse ecosystem has a
better chance in maintaining its
stability

32. ◦But how can we give a
quantitative explanation of
how diverse an ecosystem is?

33. ◦Let’s define Biodiversity
quantitatively

34. Biodiversity Indices
◦Species Richness refers to the number of species in
a particular place.
◦Species Evenness refers to the extent to which
individuals are distributed evenly among species.
◦Relative Abundance refers to the number of
individuals in a species divided by the total number of
all species.

35. Activity: Which Ecosystem is More Diverse?
◦Objective: Measure the richness,
evenness, and relative
abundance of species in a
community.

38. COMMUNITY B
Species Name # of Individuals Relative Abundance
Acacia 35 8.06%
Apitong 12 2.76%

40. EVALUATION

41. 1. Which of the following refers to the variation of genes
within the species?
◦A. Community Diversity
◦B. Ecosystem Diversity
◦C. Genetic Diversity
◦D. Species Diversity

43. 2. What is the significance of species diversity in the
stability of an ecosystem?
◦A. Different species never interact with the environment thus
making the ecosystem stable.
◦B. Different species interact with their environment and thus
perform certain functions that stabilizes the ecosystem.
◦C. Though species interact with the environment they DO NOT
perform any function.
◦D. Species minimize interaction with their environment and thus
perform certain function.

45. 3. What is the definition of biodiversity?
◦A. the study of biology in the jungles
◦B. the study of biology in a university
◦C. biochemicals in the field of science
◦D. the variety of species in the environment

47. 4. Which ecosystem is richest in biodiversity?
◦A. desert
◦B. temperate forest
◦C. temperate grassland

49. 5. What are three levels of biodiversity?
◦A. genes, cells, traits
◦B. mutation, disorder, regression
◦C. species, genetic, and ecosystem
◦D. water, land, mountains

51. ASSIGNMENT
◦½ crosswise
◦Explain how species diversity increases
the probability of adaptation and
survival of organisms in changing
environment.
