Yesterday I went on a trip to the beach. I saw several different organisms. First I saw a sea sponge. It had a body that was not symmetrical at all, which is (1). It also belongs to group of animals called (2)as they have no backbone. The sponge feeds by (3) food out of the water. This means it separates the food from the water. Then I saw a sea star that has a body with many lines of symmetry that pass through a central point called (4). I also saw a crab that has a body that is divisible into two mirror parts by a central line called (5). It also has an external skeleton or a (6). I caught a shark which controls its body temperature by external means making it a (7). The shark is a (8) or has a backbone. It also has an internal skeleton called a (9).

Sea levels are rising due to climate change while increasing numbers of people are moving into coastal areas. to accommodate more people, there has been increased construction of beachfront resorts and condominiums. how is this impacting sea turtle numbers and biodiversity and why? a. the increased human population in coastal areas has meant that more food is available to the turtles (e.g., dropped food, waste from restaurants), which has led to an increase in the numbers and diversity of sea turtles. b. there has been very little change in the numbers and biodiversity of sea turtles because the planet is so vast that they can simply relocate to less crowded beaches. c. this has resulted in a decrease in numbers and diversity of sea turtles because it is restricting available nesting sites, and hence reproduction. d. this has resulted in an increase in numbers and diversity of sea turtles because people are around to protect them from natural predators.
