1

Biodiversity refers to the variety of life on earth

How many categories can we classify biodiversity?
Name those categories

(GES)

3 types
- genetic biodiversity
- Ecosystem biodiversity
- species biodiversity

2

Complete the extract below about genetic diversity.

Genetic diversity refer to the ____________ within the _______ species . No two individuals of the ______ species are_______.

Difference in gene is due to individual __________ and _________ to different environments. This promotes the ability of species to ___________ to the environment

variation of genes
same species
same
identical

individual isolation
adaptation to different environment
adapt

3

What are the examples of genetic diversity?

- Paddy plant
- banana plants that have the ability to grow in different regions

4

Complete the extract below about the ecosystem diversity.

Ecosystem diversity refers to the _______ and ______ process in the ecosystems on the land, sea and other aquatic environments.

Example of ecosystem diversity are:
There are many _______ that can be found in the _______ or dessert .

biotic
ecological

ecosystems
ocean

5

Complete the extract below about the species diversity.

Species diversity refers to the _______ of ___________ in an ___________. Species diversity includes the __________ of a species in a _________( species richness) and the ____________ in a community.

This promotes the ___________ and stability of the community

variation
different species
area
total number
community
species distribution

biotic interaction

6

State an example of species diversity.

- Tropical rainforest

7

What is phylogeny?

- Means the evolutionary history of a species or a group of organism that are genetically linked

8

Phylogenetic classification is the classification system that shows the ____________ relationship and the __________ of the studied organism. Phylogenetic classification can be classified into _____________ and ______________

Evolutionary
history
phylogenetic tree
homologous structure

9

What is the difference between phylogenetic tree and homologous structure?

Phylogenetic tree shows the species of organisms diverge from the same ancestor

Homologous structure refers to the anatomy or body parts that can be observed across multiple organisms

10

Evidence suggest that land plants evolved from green algae. First land platns originated from non-vascular plants such as mosses followed by seedless vascular plants such as ferns.

Vascular plants then evolve to gymnosperms and angiosperms. What are the differences?

Gymnosperms- has no flowers, does not produce fruit and seeds, only produce cone

Angiosperm- has flowers and fruits

11

Why is biodiversity important for humans and the environment?

- important source of food
- maintain food chain
- prevent extinction of species

12

What are the differences between in situ conservation and ex situ conservation in Malaysia?

In situ conservation- it maintains species in their natural habitat ( National Park, permanent forest reserve)

Ex Situ- conserve species found outside of their natural habitats ( zoo, botanical garden)
