Our new unit is 3A Unit 7.7 Habitats and Environment.
Things to do / Due date is Tuesday, April 3
1. Watch the video and answer the follwing questions that you will find in the link.
- How do land plants generate the energy they need for their metabolic energy? What do they do with excess energy?
- Where do scavengers in an ecosystem obtain their energy from? How can scavenging be a beneficial strategy for an organism?
- What is the role of decomposers?
- What kind of problems can you foresee if every speck of carbon were turned into biomass? Why?
- Complete this statement: Energy ___________ through an ecosystem, whereas nutrients are ____________.
- Define an ecosystem.
- Distinguish between abiotic and biotic factors. Give examples of each.
- Where does the energy come from for many ecosystems?
- Name two nutrients that are recycled through an ecosystem.
|abiotic factor||Nonliving aspect of the environment.|
|biogeochemical cycle||Pathway of elements like carbon and nitrogen through the non-living and living parts of the ecosystem.|
|biotic factor||Living aspects of the environment.|
|consumer||Organism that must eat or consume other organisms to obtain energy and nutrients.|
|ecology||Study of how living organisms interact with each other and with their environment.|
|ecosystem||All of the living things and non-living things interacting in the same area.|
|habitat||Ecological or environmental area where a particular species live.|
|photosynthesis||Process by which specific organisms (including all plants) use the sun's energy to make their own food from carbon dioxide and water; process that converts the energy of the sun, or solar energy, into carbohydrates, a type of chemical energy.|
|population||Group of organisms belonging to the same species that live in the same area and interact with one another.|
|producer||Organism that can absorb the energy of the sun and convert it into food through the process of photosynthesis; i.e. plants and algae.|
