• 3. Define “detritivore”

• 4.Which level of the energy/biomass pyramid contains the most energy/biomass?

Community interactions

42

Community Interactions: Symbiosis

• A close and permanent association between organisms of different species

• Commensalism – a relationship in which one organism benefits and the other is not affected

• Example: Barnacles on a whale

43

Community interactions• Mutualism – a relationship in

which both organisms benefit from each other

• Example: Birds eating pest off a rhino’s back

• Parasitism – A relationship in which one organism benefits and the other is harmed

• Example: Ticks on a dog

44

Community interactions• Competition - a relationship

where both organisms compete for the same energy source

• Example: a rabbit and a deer competing for grass, plants competing for light

• Predation - a relationship where one organism preys upon another

• Example: a wolf hunting a rabbit

• Community interactions summary

Table 53.1

Notes Mini-Quiz 10/14

• 2. Give an example of organisms who engage in commensalism.

ECOLOGICAL PYRAMIDSand the Transfer of Energy in

Ecosystems

Which animals are at each level? What type of ecological niche do they each belong to?

Ecological Pyramids:graphs which illustrate the trophic levels in a community.

Most ecological pyramids are large at the base and narrow at

the top. This is because every time that an organism is eaten by the next trophic level, some of the energy is lost

as heat.

More Energy

Less Energy

3 TYPES OF PYRAMIDS:

1. Pyramid of Biomass2. Pyramid of Energy3. Pyramid of Numbers

Pyramid of Biomass:• Illustrates the amount of biomass in each trophic level

– Biomass weight is determined after dehydration

• Shows the amount of matter lost between trophic levels.

• Measured in Kg, grams or pounds

Pyramid of Biomass P

id o

f Bio

mas

s

Pyramid of Energy:• Shows the energy available at each trophic level.

– The size of the blocks represents the proportion of productivity

– Measured in Joules or Calories

Pyramid of Energy:• Most of the energy available to the community is

in the 1st trophic level.• Only 10-20% of the energy is available to the

next trophic level (≈ 90% lost)

Pyramid of Numbers:• Illustration of the number of organisms at

each level

What kind of Pyramid

is this?

Energy, the trophic levels are measured in Kilocalories

How can more people be supported on Earth when there is a limited supply of resources?

Human Population Growth

It depends on what they are eating…

Mini-Quiz 10/10

• 1. What does a biomass pyramid illustrate?

• 2. If a 150 pound animal ate nothing but plants, estimate how many pounds of plant material it takes to build 150 pounds of animal biomass.

• 3. If a 150 carnivore ate nothing but herbivores, estimate how many pounds of plant material it takes to build 150 pounds of carnivore biomass.

• 4. Which category of organisms contain the most biomass on a biomass pyramid?

• 5. Which category of organisms contain the least biomass on a biomass pyramid?


In ecology, what does it mean if an organism is a producer?

Food Chains and Food Webs

What is a food chain?

• A food chain is “a sequence of organisms, each of which uses the next, lower member of the sequence as a food source”

Important facts about food chains

• In a food chain each organism obtains energy from the one at the level below.

• Plants are called producers because they create their own food through photosynthesis

Primary Producers

• Primary producers are “organisms capable of producing their own food”

• We can also say that they are photosynthetic, use light energy.

Primary Producers

• Examples of primary producers include algae, phytoplankton, and large plants.

• Primary producers are eaten by primary consumers (herbivores)

Important facts about food chains

• Animals are consumers because they cannot create their own food, they must eat plants or other animals to get the energy that they need.

Four types of consumer

• Herbivores: animals that eat only plants.

• Carnivores: animals that eat only other animals.

• Omnivores: animals that eat animals and plants.

• Detritivores: Animals that eat dead materials and organic wastes

Other Ways to Classify Consumers

1. Primary Consumers: Herbivores3.

2. Secondary Consumers: Carnivores that eat herbivores3.

3. Tertiary Consumers: Carnivores that eat other carnivores3.

Mini-Quiz 10/9

• 1. 2 examples of producers

• 2. 2 examples of herbivores

• 3. 2 examples of carnivores

4. 2 examples of omnivores

• 5. 2 examples of detritivores
