2 5 points An example of symbiosis is a. a hawk hunting a mouse b. a school of fish swimming together c. a butterfly sipping nectar from a flower d. wolves fighting over territory
3 c. A butterfly sipping nectar from a flower.
4 10 points A remora hitching a ride on a shark is an example of _________.
6 15 points A tick sucking a dog’s blood is an example of __________.
8 20 points Aphids make a sweet substance that ants eat. The ants protect the aphids. This is an example of ____________.
10 25 points Explain how the faces represent certain symbiotic relationships.
11 Two smiles = Mutualism One smile, One no smile = Commensalism One smile, One frown = Parasitism
12 5 points The gradual change from a barren environment to a stable ecosystem is called _________.
13 Primary Succession
14 10 points After a forest fire, grasses and small shrubs begin to grow. Eventually, trees grow back. This is an example of __________.
15 Secondary Succession
16 15 points A gradual series of changes in an area’s communities is called_______.
18 20 points Moss growing in a bare rock environment is a _________.
19 Pioneer Species
20 25 points What can trigger Secondary Succession?
21 Floods or fires
22 5 points Male deer fighting over territory is an example of __________.
24 10 points Lions hunting together is an example of ______________.
26 15 points In what ways do organisms of the same or different species compete?
27 For food, water, space and other resources
28 20 points Male peacocks displaying their feathers to attract a mate is an example of ________.
30 25 points What do plants compete for?
31 Sunlight, space, water and nutrients
32 5 points What does a limiting factor do?
33 Limits the growth of a population
34 10 points What can cause a population to grow?
35 Fewer predators, more food
36 15 points It’s something that helps determine the growth of a population in an ecosystem.
37 Limiting Factor
38 20 points Nutrients are added to a waterway, causing the algae population to grow rapidly. Nutrients are a ________ for the algae.
39 Limiting Factor
40 25 points An unsually cold winter causes the squirrel population to decrease. This example of a limiting factor is the ________________.
41 Temperature decrease
42 5 points The _______________ of an environment is the maximum population that it can support.
43 Carrying Capacity
44 10 points Grazing in a herd benefits a deer population because it gives them ____________.
45 Protection from predators
46 15 points Can a organism be both prey and predator? How?
47 Yes, for example a bird that eats a caterpillar is in turn eaten by a hawk.
48 20 points An ecosystem’s carrying capacity is different for each population. Why?
49 Lower level consumers are in greater numbers because they consume primary consumers.
50 25 points Explain how symbiotic relationships are similar to and different from prey-predator interactions.
51 Prey-predator relationship, one species benefits and the other is harmed. Similar to parasitism but the parasite relies on the host for survival so they do not want to kill their host.
You will learn: About different types of interactions in an ecosystem. How some species benefit from interactions. How some species are harmed by interactions.
Competition, Predation and Symbiosis. Bellringer Name a biotic factor in a forest. Name two limiting factors for a population of lions. What is carrying.
All living things interact with their environment, both biotic and abiotic Most living things produce more offspring than can survive.

ORGANISMS CAN INTERACT IN DIFFERENT WAYS ORGANISMS INTERACT IN DIFFERENT WAYS SURVIVAL OF ONE SPECIES MIGHT DEPEND ON ANOTHER SPECIES –SYMBIOSIS = relationship.

ECOSYSTEMS (relationships and competition for limiting factors )
Chapter 18 – Interaction of Living Things. The Web of Life All living things are connected in a web of life Ecology - the study of the interactions of.
Community Ecology No organism lives alone. Each organisms affects and is affected by other species and its environment. 1.
Environment The physical surroundings of an organism, including all the conditions and circumstances that affect its development.
Interactions Within an Ecosystem Interactions is an ecosystem are influenced by the fact that all organisms are trying to meet at least one of their basic.
Objectives: 1. Students can describe the different types of interactions within an ecosystem. 2. Students describe symbiotic relationships in which.
Interactions within Ecosystems CHAPTER the BIG idea Living things within an ecosystem interact with each other and the environment. Groups of living things.
Ecological Relationships. Important Vocabulary 1.Biotic Factors: living things 2.Abiotic Factors: nonliving, physical things such as: a.Temperature, sunlight,
ECOSYSTEMS ‘A World of Interactions’. Populations What is a population? When we talk about populations what in general do we mean? A group of organisms.
1 Study of interactions of living organisms with one another and with their physical environment.
Environmental Interdependence Coexisting in an ecosystem.

Organism Interactions Alondra Del Rio 5/2/14 (there are animations on these slides so if you play the words/pictures will be legible)
Symbiosis, Competition, Predator/Prey. Because, in order to survive, a living organism depends on other living things. Why Do Living Things Interact With.
Interactions of Living Things. The environment consists of: Biotic Factors (living things) – Plants – Animals – Bacteria, fungi, protists Abiotic Factors.
Ecology. Organism Species Group of similar organisms that can breed and produce offspring. Group of similar organisms that can breed and produce offspring.
Ecosystems are always changing. Chapter 2 Section 3.
Ecology. The place an organism lives or spends most of its time is called its habitat. Habitats can be small like under a rock or large like the ocean.
Natural Selection – a characteristic that makes an individual better suited to its environment may eventually become common in that species. Natural selection.
Relationships in the Ecosystem. What are the types of relationships? 1)Predator / Prey 2)Competition 3)Symbiosis A) commensalism B) mutualism C) parasitism.
Interspecific Competition Competition for shared or scarce resources Often food or space When this occurs, one of the competing species must:
Types of Interactions Section 3. Objectives Distinguish between the two types of competition Give examples of predators and prey Distinguish between.
Anchor: BIO.B.4.2 Describe interactions & relationships in an ecosystem ◦ BIO.4.2.2: Describe biotic interactions in an ecosystem.
Symbiosis Mutualism | Commensalism | Parasitism Learning Objectives Compare and contrast the three types of symbiosis Evaluate relationships to determine.
Organisms and their Environment. 1.ECOLOGY is the study of interactions that take place between organisms and their environment.
Second lecture Carrying capacity Carrying capacity is the maximum population size that a particular environment can sustain. more food carrying less.
