Ecosystems at Risk Ecosystems and their functioning What is an ecosystem? Ecology – the science that examines the interactions between organisms and their living (biotic) and non-living (abiotic) environment. Groups of organisms and their biophysical environment interact and exchange matter and energy. Ecosystem – the dynamic complex of plant‚ animal and micro-organism communities and their non-living environment as a functional unit. Ecosystems are dynamic; constantly changing and adapting

Earth: A Living Planet To care for our planet we must understand how it opperates. Ecology is the study of interactions of organisms with one another and with their physical surroundings. Scientists who study ecology are called ecologists. Earts is a biosphere‚ or a living globe. The biosphere is that part of the Earth in which life exists. Biospheres include all the areas of land‚ air‚ and water on the planet. The biosphere goes about eight kilometers above the Earth’s surface to as far as eight

Ecology Discussion Questions Chapter 40 1. If you are a biologist interested in working in the tropical rainforest‚ briefly describe a research study you could complete at each level in the biological hierarchy‚ starting from the organismal level to the biosphere. 2. What are the two abiotic variables that dictate type of terrestrial biome? Do aquatic and marine systems rely on the same two variables? Why or why not? 3. Which of the terrestrial biomes is the most vulnerable to anthropogenic

Chapter 1 INTRODUCTION Azolla (mosquito fern‚ duckweed fern‚ fairy moss‚ and water fern) is a genus of seven species of aquatic ferns in the family Salviniaceae. They are extremely reduced in form and specialized‚ looking nothing like conventional ferns but more resembling duckweed or some mosses. Azolla is a free floating aquatic fern‚ which nowadays can be found in freshwater environments in temperate and tropical regions all over the world. It ranks among the fastest growing plants on Earth

Sex change in Aquatic Species By: Gobezai Abebe Introduction. Many species of invertebrates‚ fish and plants undergo a process which is rare and requires detailed research to understand (Allsop and West‚ 2003). The process that they undergo is known as sex change. Focusing specifically on hermaphroditic fish‚ sex change can occur in two directions. One direction that sex change can occur is the change from female to male which is known as protogyny (Allsop and West‚ 2003; Kuwamura et.al‚ 2002;

M12E Title: Cell Respiration and Aquatic Animal Aim: To investigate the effect of a change in the temperature of water on the respiration rate of a goldfish. Research question: Does a change in temperature of water affect the respiration rate of a goldfish? Introduction: “The goldfish is a domesticated subspecies of a carp like fish called Carassius auratus. Goldfish are usually kept as pets‚ feeding on fish food‚ algae‚ plankton and other small aquatic life forms. Though goldfish are one
