Suppose a new resort hotel is built on a hawksbill sea turtle nesting site, and hotel guests start removing the queen angelfish from the nearby reef to stock their home aquaria. If the hawksbill sea turtles and queen angelfish are removed, which organism is most likely to benefit?.
Answer:
Sponges, Anemones, Squid and Shrimp.
Explanation:
Those are the organisms that the sea turtle feed on.
Sponges, Anemones, Squid and Shrimp are most likely to benefit since the sea turtles and angelfish feed on them.
What happens if hawksbill sea turtles and queen angelfish are removed?Hawksbills contribute to the preservation of coral reef health. Reef fish have easier access to food because they clear sponges and other prey off the reef's surface. They are also valuable for tourism and have cultural significance.
Queen angelfish are omnivores that primarily eat algae and sponges. They are opportunistic and will consume jellyfish, soft corals, and sea fans. Young fish clean larger kinds of fish by removing parasites from their skin so that they can be eaten.
The populations of the organisms that Hawksbill Sea Turtles and queen angelfish consume, such as sponges and sea urchins, would probably explode if they became extinct. This would result in widespread erosion and possibly the collapse of marine ecosystems like coral reefs.

C. a push and a pull
D. All of the above
Explanation:
push is the application of force to move something closer..
Point, . push ,a push and a pull is the application of force to move something closer.
Option (D) is correct.
When you apply force to move an object, there are generally two ways to do it: pushing or pulling.
1. Pushing: This is when you exert force on an object away from you, causing it to move in the direction of the force. For example, if you push a chair forward, you apply force in the direction away from you, making the chair move forward.
2. Pulling: This is when you exert force on an object towards you, causing it to move in the direction of the force. For instance, if you pull a door towards you, you apply force in the direction towards you, making the door move inwards.
So, the application of force to move something closer can involve either pushing or pulling. Therefore, the correct answer is "All of the above" (D), as both A (push) and B (pull) are correct ways of applying force to move something closer.
