1. 01
   Population Interactions Worksheet Grade 7 Science Ecosystems Activity

   Grade 7 · Science · 32 Pages

   • Explain how predators, prey, and competitors affect access to resources in a community
   • Describe how mutualism can change resource availability and improve survival for both partners
   • Connect population interactions to changes in survival, reproduction rates, and population size over time

2. 02
   Matter and Energy Flow Worksheet Grade 7 Science | Ecosystems Activity

   Grade 7 · Science · 30 Pages

   • Explain how matter and energy move through ecosystems using producers, consumers, and decomposers.
   • Describe how energy is transferred through food chains and webs and why less energy reaches higher trophic levels.
   • Connect metabolism and heat loss to the decreasing amount of usable energy at each trophic level.

3. 03
   Decomposer Recycling Worksheet Grade 7 Science | Nutrient Cycles Activity

   Grade 7 · Science · 30 Pages

   • Explain how decomposers return nutrients to soil and water by breaking down dead organisms and waste.
   • Describe how decomposition supports the continuity of matter in an ecosystem.
   • Identify the roles of decomposers such as fungi and bacteria in nutrient recycling.

4. 04
   Cell Energy Use Worksheet Grade 7 Science | Cellular Processes Activity

   Grade 7 · Science · 31 Pages

   • Explain how cells convert chemical energy in food into usable energy for life functions
   • Describe how cells use energy to support movement, active transport, and maintaining body temperature
   • Model energy and matter changes by explaining that energy changes form while matter is conserved

5. 05
   Resource Availability Worksheet Grade 7 Science | Ecosystems & Population Growth

   Grade 7 · Science · 31 Pages

   • Explain how limited resources affect survival and reproduction in an ecosystem.
   • Describe how population sizes change when resources are abundant versus scarce.
   • Use evidence and scientific reasoning to make predictions about population changes.

6. 06
   Photosynthesis Capture Worksheet Grade 7 Science Practice & Activities

   Grade 7 · Science · 30 Pages

   • Explain how photosynthesis converts light energy into chemical energy stored in sugars
   • Identify the inputs and outputs of photosynthesis and describe where the process happens
   • Connect photosynthesis to how matter and energy move through food chains
   $4.00$5.00Preview
7. 07
   Matter Cycling Worksheet Grade 7 Science Activities | Ecosystems & Matter

   Grade 7 · Science · 30 Pages

   • Explain how atoms move through an ecosystem during matter cycling processes such as photosynthesis, respiration, feeding, and decomposition.
   • Describe how decomposers return nutrients to soil and water so that new plants can grow.
   • Distinguish matter cycling (reused atoms) from energy flow (one-way transfer with heat loss).
   $4.00$5.00Preview
8. 08
   System Structure Worksheet Grade 7 Science Body Systems Practice

   Grade 7 · Science · 32 Pages

   • Explain how organisms function as systems made of internal structures with specific roles.
   • Identify how different body systems process inputs like food, oxygen, and water.
   • Describe how the coordinated functions of structures help the organism use matter for life processes.

9. 09
   Nutrient Transport Worksheet Grade 7 Science Activities | California Standards

   Grade 7 · Science · 30 Pages

   • Explain how internal transport moves materials from where they are obtained to where cells need them.
   • Describe how the body removes unusable materials to prevent harmful buildup.
   • Use models and vocabulary to connect digestion, circulation, and waste removal.

    Trophic Energy Transfer Worksheet Grade 7 Science Food Web Activity

    Grade 7 · Science · 30 Pages

    • Explain how energy transfers through trophic levels in a food web.
    • Describe why only a few trophic levels can be supported by available energy and biomass.
    • Distinguish between producers, consumers, and how energy transfer efficiency affects predator populations.
