-
How is nitrogen both removed from the atmosphere and returned from the atmosphere
- Plants and animals
- Bacteria
-

How does biodiversity contribute to the sustainability of an ecosystem?
Biodiversity creates a stable ecosystem because then if a crisis happens that endangers a species there are other species to take its place

Primary Succession
Occurs when no soil is present
-
Primary species
First organisms to live in the area
-
Organisms that live on bare rock
Moss and lichen
-
What happens when moss and lichen grow
They release acid that breaks down the rock and forms soil
-
What happens when moss and lichen die
Their remains are broken down and added to the broken down rock to create soil
-
When do bushes and ferns appear based on succession
When the moss and lichen have formed enough soil.
-
What happens when ferns and bushes die.
Their remains add nutrients to the soil.
-
Based on succession what comes after buses and ferns
shrubs, trees, insects, birds and mammals
-
Secondary succession
Occurs when bare soil is present. The soil already contains nutrients of weeds, grasses and trees.
