With this knowledge, you will determine how abiotic factors like water temperature, water clarity, carbon dioxide, and oxygen affect the kelp since they form the base of food pyramids as producers. Answer KeyDo you ever look at a picture and wonder what its story is? The distance at which the disk disappears is the water clarity reading, which is recorded in centimeters. Orcas are particularly vulnerable to pollution because they live at the top of the food chain. Orcas are still hunted in some countries, such as Greenland. What is the Relationship Between Water Clarity and Urchin Survival. The large size of a killer whale helps minimize heat loss. Additionally, rising temperatures can cause stress and health problems for orcas, as well as reduce their ability to reproduce successfully. Why Is Water Clarity Important For Orcas? In addition, warmer water can lead to increased parasites that can harm orcas. (Elaine Thompson/AP) In the Salish Sea off .

Variation in water clarity over the northern shelf is notable because primary production here typically continues throughout the summer by virtue of high surface clarity. Orcas, also known as killer whales, are one of the most fascinating and intelligent animals in the world. It profoundly influences the structure of marine ecosystems, from plankton to predators. Orcas rely on a healthy supply of fish to survive. There is a strong relationship between temperature and orca survival. For example, clearer water allows more sunlight to reach submerged aquatic vegetation. ?an environmental value is lower or negligible.
