How are organisms of the Chesapeake Bay ecosystem interdependent upon each other and their environment?

Food Chains in the Chesapeake Bay

What organisms are considered producers, consumers or decomposers in this ecosystem?

All living things need energy to grow, develop and

survive. In order for these life cycles to take place, there

are a series of energy transformations which occur

between the biotic and abiotic factors in an ecosystem.

What is the energy relationship between producers,

consumers and decomposers?

2. Information Sources You will review the following e-resources in order to explore the energy

relationships in the Chesapeake Bay ecosystem. Be sure to verify with your teacher what star that you will be for the activity.

6. Teacher Support MaterialsBCPS CurriculumSWBAT identify the transfer of energy among organisms IOT explain how

the amount of energy remains constant in an ecosystem.Maryland State Curriculum:

Environmental ScienceThe student will demonstrate the ability to use the scientific skills and

processes (Core Learning Goal 1) and major environmental science concepts to understand interrelationships of the natural world and to analyze environmental issues and their solutions.

Indicator 6.2.1 The student will explain how organisms are linked by the transfer and transformation of matter and energy at the ecosystem level. At least —

– Photosynthesis/respiration – Producers, consumers, decomposers – Trophic levels – Pyramid of energy/pyramid of biomass

Common Core State Standards Reading: 1. Read closely to determine what the text says explicitly and to make logical inferences from it; cite specific textual evidence when writing or speaking to support conclusions drawn from the text.Writing: 7. Conduct short as well as more sustained research projects based on focused questions, demonstrating understanding of the subject under investigation.

Standards for the 21st Century Learner1.1.6 Read, view, and listen for information presented in any format (e.g. textual, visual, media, digital) in order to make inferences and gather meaning.2.1.3 Use strategies to draw conclusions from information and apply knowledge to curricular areas, real-world situations, and further investigations.

Maryland Technology Literacy Standards for Students3.0 : Use a variety of technologies for learning and collaboration.

Time Frame: 1-2 50 min class sessions

Differentiation: • Direct students to use comprehension tools included in

databases, such as: audio read-aloud, labeled reading levels, and embedded dictionaries.

Learning Styles:

Notes to the teacher: For the assessment, ensure that the students enable the macro by clicking on the icon in the formula bar.
