ECOLOGY PRESENTATION

PRIMARY SUCCESSION IS...

• The process of rebuilding an area
• The area has no soil to grow life
• There are rocks to begin the cycle

SECONDARY SUCCESSION IS...

• Process of rebuilding an area after disturbance
• There IS soil to begin the process

THE PROCESS

• Rock to lichen to soil
• To grass to trees
• To Insects to small animals to large animals
• To a happy ecosystem!

ANIMAL ADAPTATION

• Characteristics that help animals survive
• Ex. Thorny Devil
• (Has thorns to defend itself)
• Ex. Arctic Fox
• (Has bushy tail to help keep itself warm at night)

PLANT ADAPTATION

• Characteristics that help plants survive
• Ex. Palm tress/coconut trees
• (Grows near water to absorb it)
• Ex. Bamboo
• (Grows really fast and tall to get as much sun and rain)

TROPISM

• The turning of parts in a plant to the main elements
• 1. Phototropism (solar)
• 2. Hydrotropism (water)
• 3. Gravitropism (gravity)

PHOTOTROPISM

• Type of tropism
• When the plant grows toward the sun

HYDROTROPISM

• Type of tropism
• Plants that grow toward water

GRAVITROPISM

• Type of tropism
• Plants that grow downward
• (Down the direction of gravity)
