Biology Excursion Question Using data collected on field trip and two named animals, explain the relationship between the distribution and abundance of these two organisms and the abiotic features of the rock platform. There is a close relationship between the abundance and the distribution of organisms living amongst the long reef platform. Abiotic features such as temperature range, salinity, Ph. levels, turbidity, water availability effect the distribution and abundance of aquatic sea creatures living in the area. Some of the organisms such as Tesseropora Roseas (Barnacles) and Knobbly Winks have different adaptations, which allow them to survive in these harsh conditions.
There are many different species of Algae which can range in size from microscopic to a couple meters long. Phytoplankton is at the bottom of the food chain and is eaten by small crustaceans which are called Zooplanktons. Zooplanktons are eaten by fish, invertebrates, mollusks, ducks, and turtles. • Plants: Around fifty species of food and shelter providing plants- Plants along with Algae provide the Rideau River with oxygen. Some of the plants in the Rideau River are carnivorous.
a) Biotic describes a living component of a community; for example organisms, such as plants and animals. b) abiotic components (also known as abiotic factors) are non-living chemical and physical factors in the environment which affect ecosystems. c) Herbivores are organisms that are anatomically and physiologically adapted to eat plant-based foods. Herbivory is a form of consumption in which an organism principally eats autotrophs such as plants, algae and photosynthesizing bacteria. More generally, organisms that feed on autotrophs in general are known as primary consumers.

This are all situated in the Sydney Olympic Park.The Parramatta River flows through the Homebush Bay and is home to many species of birds and fish. Sydney Olympic Park was in the top 5
Besides the various pond insects that we all know, there are a large number of microorganisms in pond water. The best method of identifying microorganisms in pond water is to collect some pond water and observe it under a microscope. There are many different types of micro organisms. 5 types are bacteria, fungi, protozoa, viruses and algae. Some are unicellular and some are multi cellular.

Paramecium bursaria chauffeurs the algae and in return, the algae shares the food it produces (Palmer). This is essentially what happened with endosymbiosis. Scientists believe mitochondria and chloroplasts originated from larger prokaryotic cells engulfing bacterial cells, whereas most membrane-enclosed organelles, such as the nucleus, ER, and Golgi, likely originated from
While I was doing research, I identified the species I found. The primary producers were Nori Seaweed, Black Pine, and Coral Weed. The sessile consumers consisted of Mussels, Acorn Barnacles, and Goose Neck Barnacles. The mobile consumers happen to be Whelks, Chiton, Starfish, and Green Crabs and they
The plants release dissolved oxygen and harbor fish and shellfish (Franklin, 2001). They swim in large schools close to the water’s surface. Throughout the spring, the schools of younger, smaller fish are found in estuaries, such as the Chesapeake Bay, and the larger, older fish are found further offshore and up north. Menhaden also play an important role to the fisheries, especially along the Atlantic and Gulf coasts. Humans don’t actually
They teach the local students about the environmental concerns linked to the marine ecosystem. Field work is common for this job. The study of saltwater organisms and their relationships to their environment is also a job a marine biologist will be doing. Subject areas are almost limitless. They also study the population fluctuation in different fish.
