Emptying an aquarium containing non-native species into a local waterway
Cutting down a small cedar tree to make holiday decorations
Cleaning the windshield of a car with an alcohol-based glass cleaner

During ecological succession, how does the growth of young hardwoods affect the organisms living in an ecosystem?

Grasses and low shrubs are unable to obtain the amount of light they need to survive, so there are small numbers of them.
The trees provide shelter and food for a variety of mammals, insects, and birds.
In autumn, falling leaves provide a source of energy for decomposers such as fungi.
All of the above

The organisms that are both secondary and tertiary consumers in this food web, Ratfish, and octopuses. This is because if Galatheid crabs and Zoarcid fish are removed, they become secondary consumers, but now they are tertiary consumers.

What do you mean by Tertiary consumers?

Tertiary consumers may be defined as a carnivore at the topmost rank in a food chain that forages on other carnivores.

The statement that most likely causes the greatest disruption to an ecosystem is, cutting down a small cedar tree to make holiday decorations.

During ecological succession, the growth of young hardwoods affects the organisms living in an ecosystem by all of the statements given above.
