Which species helps in maintaining the balance of marine ecosystems by feeding on sea urchins and preventing them from overfeeding on kelp?

• Sea otters

• Sea lions

• Sea turtles

• Sea horses

Due to their sensitivity to environmental changes, which species can be used as a reliable indicator of air and water quality?

• Elephant species

• Frog species

• Lion species

• Shark species

Which of the following is a characteristic of mangrove trees?

• They are unable to survive in brackish water

• Their roots do not provide shelter for marine species

• They are unaffected by human activities such as tourism and shrimp farming

• Their leaves can excrete excess salt from brackish water

Which of the following is not a characteristic of secondary succession?

• It occurs in areas where a community that previously existed has been removed

• It begins with a completely barren environment

• It is faster than primary succession

• It often begins with species that are fast-growing

What is a common trait of pioneer species?

• Slow growth rate

• Require low light conditions

• Rapid reproduction

• Produce small seeds and dull flowers

A species has been introduced into a new environment and it multiplies rapidly due to the absence of natural enemies. This species can be best described as:

• Indicator species

• Endemic species

• Invasive species

• Keystone species

What can you observe using a line transect method?

• The boundary of the study area

• The transition between different habitats

• A subset of species present in the area

• The total population of species in the area

What two factors are represented in a climatogram?

• humidity and wind speed

• temperature and rainfall

• soil type and vegetation

• altitude and latitude
