1 Ecological Succession Ecosystems are constantly changing Changes can start after quick disturbances, like a wildfire or volcano erupting. Changes can be slow and gradual, where older species die out and newer ones replace them.
2 2 Types of Ecological Succession 1. Primary Succession essentially starts on rock. Pioneer Species the first species to grow on the rock, usually lichen. 2. Secondary Succession occurs after natural events like weather or wildfire OR after human activities like farming. Climax Communities mature ecosystems containing a stable collection of plants and animals.

9 Relationships in Communities Niche Predation Competition Symbiosis Biosphere Biome Individual Population Community Ecosystem
10 Niche: the role an organism has & the environmental conditions it needs to survive.
11 Predation (predator-prey prey relationship) one organism captures and feeds on another organism. Example: bears catch and eat salmon
12 Competition 2 organisms compete for limited resources, such as food, water, or territory. Example: bullfrogs & foothill yellow legged frog compete for food.
13 Symbiosis: : organisms that are living together 3 Types of Symbiotic Relationships:
14 1. Mutualism Both organisms benefit from the relationship Example: Otters and Kelp The otters help the kelp by eating the sea urchins that endanger the kelp. The kelp provides an anchor for the otters while they sleep.
15 2. Commensalism One species benefits & the other is not affected. Example: bluefin shark & yellowtail fish Yellowtail fish brush against sharks to get rid of old scales or parasites on their scales. The sharks are not affected.
16 3. Parasitism One organism benefits while the other is harmed. Example: Ticks on dogs Ticks attach to and feed on a host organism like this dog. Ticks may also carry diseasecausing organisms.
17
18 Review Identify the correct definition Mutualism is a relationship where? One organism benefits and the other is unaffected.? Both organisms benefit.? One organism benefits and the other is harmed. The cleaner fish eats parasites and food bits out of the inside of this moray eel. It gets a meal and is protected from predators by the fierce eel.
19 Review Identify the correct definition Commensalism is a relationship where? One organism benefits and the other is unaffected.? Both organisms benefit.? One organism benefits and the other is harmed. The oak gall wasp stings the oak tree. The tree then grows a gall which is a nest for the wasp s babies. Does not help or hurt the oak tree
20 Review Identify the correct definition Parasitism is a relationship where? One organism benefits and the other is unaffected.? Both organisms benefit.? One organism benefits and the other is harmed. Mistletoe is a parasite that has no roots of its own and lives off the tree that it attaches itself to. Without that tree it would die. It slowly chokes out the life of the host tree.
21 Lichen Mutualism? Commensalism? Or Parasitism? Lichen is really two organisms: algae and fungus. The fungus needs food but cannot make it. The algae makes food but needs some way to keep moist. The fungus forms a crust around the algae which holds in moisture. Both organisms benefit.
22 Barnacles and Whales Mutualism? Commensalism? Or Parasitism? Barnacles need a place to anchor. They must wait for food to come their way. Some barnacles hitch a ride on unsuspecting whales who deliver them to a food source. This does not effect the whale in any way.

24 How Populations Grow Natural populations don t always stay the same size They might grow quickly OR they might decrease in size. Population Density is one characteristic of populations: The number of organisms that live in a specific area. 4 factors affect population size: Number of births Number of deaths Immigration (individuals moving INTO an area) Emigration (individuals moving OUT of an area)
25 How Populations Grow Population Growth Curves: Exponential Growth: unrestricted growth Exponential Growth Logistic Growth: restricted growth Carrying Capacity: the maximum number of individuals that can be supported in an area. Logistic Growth
26 Limiting Factors to Population Growth Density Independent Factors: environmental factors that don t depend on the population density. Ex: weather, fire, human activity Density Dependent Factors: factors that DO depend on the population density. Ex: disease, competition, parasites
