PPT-Semester 1: Unit 2: Energy Flow in Ecosystems:

Photosynthesis and Cellular Respiration Energy is the ability to do work Without ability to obtain amp use energy life would NOT exist One of the most important compounds that cells use to store amp release energy is . Assessment Statements. Define species, habitat, population, community, ecosystem, and ecology. Distinguish between . autotroph. and . heterotroph. Ditinguish. between consumer, . detritivores. and . Tundra. Swamps. Ocean/Shore Line. Desert. Mountains. S:\FACULTY\6th Science\Introduction to ecosystems.asf. Ecosystem:. All of the living and non-living things that interact in an area.. G:\SECONDARY SCIENCE\Middle School\6th Grade\Ecosystems1\Ecosystems.asf. Miller chapters 3 & 4, 18. th. Ed.. Day 1. Goals. Students complete virtual owl pellet lab. Students can explain owls’ role in a food web. Students can define. Producer, consumer, decomposer. Students can draw: food web, food chain. Ocean Acidification: . How does changing ocean chemistry affect ocean ecosystems?. Jim Barry, Monterey Bay Aquarium Research Institute. Benthic Respiration Chamber System. Perturbation experiments in the deep-sea.                       . Ecology. – the study of the relationships between organisms and their environment. Ecosystem. -- a community of organisms and their nonliving environment. Every organism requires energy to carry out life processes such as growing, moving, and reproducing. Photosynthetic . producers. such as plants convert the light energy from sunlight to the chemical energy of organic compounds. . The word . photosynthesis. can be broken down to its Greek origin: . Synthesis . “put together to form something new” and . Photo. “light.”. The most important aspect of photosynthesis is that . Chapter 3 (Miller and . Spoolman. , 2010). Core Case Study: Tropical Rain Forests Are Disappearing. Cover about 2% of the earth’s land surface. Contain about 50% of the world’s known plant and animal species. Reversing the Deforestation of Haiti. People use charcoal for fuel:. In 1923, 60% of country was covered in forest. Now, less than 2% remains forested. Disrupts ecosystem services that trees provide.. What are Ecosystems? . Groups of living things and the non-living environment in which they live.. The people that study ecosystems are called: . “ecologists.”. Let’s look at the living parts of the ecosystem:. Section 3: . Aquatic Ecosystems. K. What I Know. W. What I Want to Find Out. L. What I Learned. Essential Questions. What are the major abiotic factors that determine the aquatic ecosystems?. What are transitional aquatic ecosystems and why are they important?. Before, you learned. • Matter cycles continuously through an ecosystem . • Living things are part of the water, carbon, and nitrogen cycles. Now, you will learn. • How living things move energy through an ecosystem . Dr.Seema Keswani. Assistant Prof. & Head.. Dept. of Zoology. Trophic Levels. The primary source of energy for an ecosystem is the sun. . Photosynthetic organisms, such as plants and algae, change light energy from the sun into energy that they can use to grow. . Ghorpade.
