Part 2: The nutrient cycle in the rainforest Flashcards
- What is nutrient cycling?
a. The way nutrients transfer between stores
- What is a store?
a. Where nutrients are stored e.g. trees
- What is a transfer?
a. How nutrients move between stores e.g. leaching
- Which stores are there in a rainforest ecosystem?
a. Biomass (plants)
b. Soil
c. Litter
a. Biomass (plants)
b. Soil
c. Litter
a. Precipitation
b. Fallout
c. Growth
d. Decay
e. Weathering
f. Leaching
- What is nutrient cycling like in the rainforest?
a. Very fast
- What is soil like in the rainforest?
a. Thin
b. Not very fertile
- Where are most of the nutrients stored in the rainforest?
a. In the plants
- Which transfer takes nutrients from the soil to the biomass?
a. Growth
- Why are the nutrients in the rainforest mostly in the plants?
a. Plants grow fast because it is hot and wet
b. They draw nutrients from the soil all year round
- Which transfers add nutrients added to the ecosystem?
a. Precipitation
b. Weathering
- Which transfers remove nutrients from the ecosystem?
a. Leaching (runoff)
- What is leaching (runoff)?
a. When water washes away nutrients
- Why is there more leaching in the rainforest?
a. Weathering is faster in a hot, wet climate
- How do nutrients move from plants to soil?
a. Fallout
b. As litter
- What is litter?
a. Leaves and parts of trees which fall to the ground
- What is biodiversity?
a. The amount of different plant and animal life in a place
- What is biodiversity like in the rainforest?
a. Hot and wet climate is good for plants to grow
b. More animals because more plants to eat
- What is net primary productivity (NPP)?
a. How much biomass is produced each year
- What is NPP like in the rainforest?
a. High
- Why is NPP high in the rainforest?
a. Warm and wet
