Species that normally lives and thrives in a particular area.
keystone species
endangered species
native species
indicator species
extinct species
The variety of organisms in a given area is called:
a species
a gene
abiotic factors
biodiversity
The diversity of organisms, whether microorganisms, animals, or plants is known as
biodiversity
habitat
climate
How can humans best help an endangered species avoid extinction?
they can feed the animals
they can put the animals in a zoo
they can protect the animal’s habitat
they can take the animal to new habitats
Example of endemic species in Malaysia is
Cat
Monkey
Malayan Tiger
What is an endemic species?
Species that can be found anywhere
Animals that became endangered
Organisms that can only be found in restricted habitat or a specific location
Plants that can undergo photosynthesis
What is the main focus of the research question?
The impact of habitat size reduction on species diversity.
The effect of pollution on air quality.
The growth rate of plants in different soils.
The migration patterns of birds.
Which of the following best describes species diversity?
The variety of species within a habitat or a region
The number of individuals in a species
The genetic variation within a species
The number of ecosystems in a region
What is the primary factor that contributes to high species diversity in tropical rainforests?
High levels of sunlight
Abundant water supply
Stable climate conditions
Rich soil nutrients
Which of the following is a method used to measure species diversity in an ecosystem?
Species richness
Species evenness
Both species richness and evenness
None of the above
How does species diversity contribute to the stability of an ecosystem?
By increasing competition among species
By providing a variety of food sources
By reducing the number of predators
By promoting genetic uniformity
Which of the following human activities is most likely to decrease species diversity?
Deforestation
Reforestation
Establishing wildlife reserves
Pollution control
In an experiment, a scientist observes that an increase in plant species diversity leads to an increase in insect diversity. What is the most likely explanation for this observation?
Insects prefer diverse plant species
More plant species provide more habitats and food sources
Insects are attracted to specific plant species
Increased plant diversity reduces competition among insects
Which of the following is an example of a keystone species that affects species diversity in its ecosystem?
Sea otter
House cat
Pigeon
Goldfish
Why is it important to maintain species diversity in agricultural systems?
To increase crop yield
To reduce the need for fertilizers
To enhance pest and disease resistance
To simplify farming practices
