Eco Relationships “Instas” Divide your paper to create 4 boxes. In each box, draw an “insta” for each type of ecological relationship (Think about how Instagram works…the picture should describe the relationships) Predation, Mutualism, Commensalism, and Parasitism Include a caption that also describes the relationship

Essential Question How do ecosystems develop and change over time? Standard B.11D - Describe how events and processes that occur during ecological succession can change populations and species diversity. PG 131

Think – Pair – Share What kinds of things do people do to cause changes in their environment? What kinds of things happen naturally to cause changes in the environment?

What is succession? Succession is when one thing follows another in a particular sequence. Ecological succession: when ecosystems go through a series of predictable changes after a disturbance

Mount Saint Helens

The series of predictable changes that occurs in a community over time is called ecological succession.

Succession that occurs on surfaces where no soil exists is called primary succession.

Primary = First = 1 = Back to Square 1

Two geological events that could lead to primary succession are volcanic eruptions and the melting of glaciers.

The first species to populate a new area are called pioneer species.

Pioneer species prepare an ecosystem for new species by helping to form soil in which plants can grow.

Secondary succession follows when a disturbance of some kind changes an existing community without removing the soil.

Secondary succession might be caused by wildfires, hurricanes, or tornados.

Succession affects organism populations in two ways: DENSITY: The total number of organisms living in a particular area DIVERSITY: The number of different species living in a particular area (also called biodiversity) more diverse ecosystems are healthier As succession proceeds, both density and BIOdiversity will increase.

A climax community is a mature, stable community that does not undergo further succession.

Plant and animal life returns to an area in a predictable order after a natural disaster: 1.FIRST (primary succession): a)pioneer species (lichens) grow on the exposed rock b)no animal life exists 2.SECOND (secondary succession): a)small plants like grasses replace pioneer species as soil begins to develop b)small plant-eating animals return to the area 3.THIRD (secondary succession): a)medium-sized plants like shrubs return as the soil becomes richer b)larger plant-eaters and small meat-eaters return 4.FOURTH (secondary succession): a)large plants like trees return as the soil become nutrient-rich b)large meat-eating animals return
