The cod (kabeljauw) feeds on the lodde, a tiny fish that feeds on animal and plant based plankton

To which 2 links can you ‘assign’ the cod (kabeljauw)?

1. Producer, consumer
2. Primary consumer, secondary consumer
3. Secondary consumer, tertiary consumer
4. Tertiary consumer, detrivore

Menno states: a pyramid of numbers is always a pyramid shape
Wilco states: the last link in the foodchain always has the most biomass
Which statement(s) is/are correct?

1. Both are correct
2. Only Menno is correct
3. Only Wilco is correct
4. None are correct

What is the function of bacteria and fungi in the nutrientcycle?

1. They fotosynthesise
2. Clear up non biodegradable waste
3. Are consumers
4. Convert waste into plant available nutrients

Biotic

Abiotic

Sunlight

Parasites

Detrivores

Temperature

Soil composition

Plants

What level of ecology would you put all the organisms in a woodland?

1. Ecosystem
2. Community
3. Population
4. Individual

The carbon cycle... which arrow indicates photosynthesis?

In which way is energy 'lost' in an ecosystem?

Which organism could be at number 1?

1. Water beetle
2. Pike (predatory fish)
3. Vegetable plankton
4. -

All of the following statements concerning characteristics of predator-prey relationships are
correct EXCEPT:

1. A rise in the population of prey is often followed by a rise in the population of predators.
2. A rise in the population of predators is followed by a decrease in the population of prey.
3. The production of large numbers of offspring within very short periods of time ensures the survival of some prey populations.
4. The population of predators most often eliminates the population of prey.

Does deforestation contribute to global warming?

1. No, trees aren't that important
2. Sometimes because only the cutting down of Maple trees contributes to global warming
3. No, deforestation adds methane to the atmosphere, which makes the Earth cooler
4. Yes; less trees means less CO2 is turned into oxygen.

What are the consequences of climate change?

1. Oceans warming and sea levels rising
2. More extreme weather patterns
3. Growing crops for food becomes more difficult
4. Health problems
