- Q1
Which changes the carrying capacity of the ecosystem?
Occurrence of typhoon
Stability of ecosystem
Ecological succession
Increase in insect population
30sS10LT-IIIh-41 - Q2
Which BEST describes carrying capacity?
Factors like food, shelter, and energy used by the number of species in an ecosystem
Number of organisms living together in an area
Maximum number of species that can be supported by an ecosystem
Types of organisms that can be supported by an ecosystem
30sS10LT-IIIh-41 - Q3
Assume that there are 3400 butterflies of a specific species living in the forest. What do the 3400 butterflies mean?
Number of species
Carrying Capacity
Population Growth
Population Size
30sS10LT-IIIh-41 - Q4
It is observed that the population growth of an organism increases rapidly when the population size is below carrying capacity. Which part of the graph shows this observation?
Year A to B
Year B to C
Year B to D
Year A to C
30sS10LT-IIIh-41 - Q5
What happened to the population size from Year B to C?
Nothing happens
Decline
Increase
Steady
30sS10LT-IIIh-41 - Q6
What is most likely to happen when a species of fish is introduced in a river?
The introduced fish becomes the native fish in the river.
The number of introduced fish in the river will not survive.
The population of introduced fish increases rapidly.
The population of native fish decreases because they have a new competitor to the resources.
30sS10LT-IIIh-41 - Q7
The population size of rats in the field increased and exceeded its carrying capacity. What is the impact of this on the ecosystem?
Increase in the number of preys
Increase in the carrying capacity of an ecosystem
Stable competition among the rats
Scarcity of resources
30sS10LT-IIIh-41 - Q8
Why does population growth decline when population size reaches the carrying capacity of the ecosystem?
Birth rate decreases due to climate change.
Organisms with a high population are easy to be found by predators.
An ecosystem has the factors that limit population growth.
Death rate increases due to scarcity of resources.
30sS10LT-IIIh-41 - Q9
What is the possible impact of the declining number of native trees in the forest ecosystem?
Other plants will have more food.
Increase the resiliency of the forest.
Decrease in the shelter of native birds and other animals.
Other organisms depending on native trees will look for other alternatives in the forest.
30sS10LT-IIIh-41 - Q10
Which is NOT needed to maintain the carrying capacity of the ecosystem?
Resources
Native organisms
Strong winds
Climate
