State the name of these six terms: 1.) a group of organisms that can interbreed and produce fertile offspring; 2.) the environment in which a species normally lives or the "address" of an organism; 3.) a group of organisms of the same species who live in the same area; 4.) a group of populations in the same area; 5.) a community and its abiotic environment; 6.) the study of relationships between biotic and abiotic factors in an environment.
What is What is 1.) species; 2.) habitat; 3.) population; 4.) community; 5.) ecosystem; 6.) ecology
100
The embryo of a land plant.
What is a seed
100
These are hard veins that transport water.
What is xylem
100
The first growth of a plant from a seed.
What is germination
100
Draw how energy and nutrients enter, move through, and exit a food chain in an ecosystem. Include an example of each trophic level.
Sun → Plant → Frog → Fish → Walrus → Polar Bear

Distinguish between autotroph and heterotroph
What is when an autotroph is an organism that synthesises its organic molecules from simple inorganic substances, where a heterotroph is an organism that obtains organic molecules from other organisms
200
This is the advantage of having a seed that can be carried to new places.
What is dispersal
200
These are soft veins that transport sugar.
What is phloem
200
A hormone that causes a plant to bend toward the light.
What is auxin

Distinguish between consumers, detritovores and saprotrophs
What is What is a consumer is an organism that ingests other organic matter that is living or recently killed, where a detritovore is an organism that ingests non-living organic matter, and where a saprotroph is an organism that secretes digestive enzymes and absorbs the products of digestion.
300
Uses water and carbon dioxide to produce sugar.
What is a leaf
300
A plant that needs a long night in order to grow.
What is a short day plant
300
Draw a labelled diagram to show the arrangement of tissues in a leaf.
Explain the energy flow in a food chain, how much is lost between each level and two reasons why.
What is What is an average loss of 90% of the energy as you move up successive trophic levels due to 1.) material not consumed or assimilated; 2.) and heat loss through cell respiration.
400
The structure that supports the plant. Green and flexible in herbaceous plants, filled with bundles of xylem and phloem.
What is a stem
400
The part of a plant that absorbs water and minerals, stores food, and anchors the plant.
What is a root
400
Draw and label plan diagrams to show the distribution of tissues in the stem and leaf of a dicotyledonous plant. (6)
