Ecosystems at every scale: interrelationships, balance and global distribution
What does it mean to say an ecosystem is in balance?
Show the answer
That the numbers of plants, animals and decomposers stay roughly stable over time because the flows of energy and nutrients between them are in equilibrium. -
Ecosystems at every scale: interrelationships, balance and global distribution
Why is temperate grassland almost treeless, and how do its seasons differ from the savanna?
Show the answer
Its rainfall is too low and unreliable for trees, so grasses dominate, and instead of a hot wet and dry season it has warm summers and cold winters.
The 1 subtopics
One subtopic is one session. Work down the list.
| Subtopic | What it covers | Questions |
|---|---|---|
| Ecosystems at every scale: interrelationships, balance and global distribution | Producers, consumers and decomposers, food chains, food webs and nutrient cycling, how an ecosystem stays in balance and what happens when one part changes, Epping Forest as a small UK woodland ecosystem, and the world's major biomes. | 26 |
How the guide is worked
Answering a question from memory stores it far better than reading the answer again. The guide runs that as a fixed procedure on one subtopic at a time, about twenty minutes a session.
-
Step 1 · Closed book
Cover the answers. Work through one subtopic and write down what you can. Leave blanks where you have nothing.
-
Step 2 · Open book
Go back to the top. Read each printed answer and write it out in full, including the ones you had right.
-
Step 3 · Closed book again
Same questions, same order, from memory. The gap between pass one and pass three is the session result.
Read the full method, the return schedule and the research behind it.
