Ecosystem Interactions and Microorganisms

The video discusses how various factors like water levels, temperature, and climate change impact ecosystems and species populations. It explains that suitable climate conditions can lead to population growth, while unsuitable conditions can cause declines. An example of seabirds illustrates how changes in the marine food web, driven by climate change, affect species survival. As water warms, microorganisms move, causing a chain reaction that impacts fish and seabirds, leading to migration or death.

What are some factors that can affect an ecosystem?

• Water levels and temperature

• Soil type

• Wind speed

• Amount of sunlight

How does a suitable climate affect a species' population?

• It decreases the population

• It causes species to migrate

• It has no effect

• It increases the population

What happens when the population of one species changes in an ecosystem?

• It only affects that species

• It causes the ecosystem to collapse

• It affects the population of other species

• It has no impact on the ecosystem

Where do seabirds build their nests?

• On mountain cliffs

• In trees

• In caves

• On the beach

What do small fish feed on in the marine food web?

• Plankton

• Microorganisms

• Seaweed

• Coral

What role do microorganisms play in the marine food web?

• They are predators

• They are producers

• They are decomposers

• They are consumers

What happens to microorganisms if the water becomes warm?

• They thrive

• They become predators

• They move to cooler areas

• They die

What is the consequence for seabirds if small fish move to a new habitat?

• Seabirds will find new food sources

• Seabirds will become predators

• Some seabirds will move or die

• Seabirds will increase in number
