Understanding Ecology: Relationships

What is Ecology?

🌎 the study of how living

things interact with their

environment

🌎 made up of biotic

(living), such as insects,

algae, animals, and

abiotic (nonliving)

things, such as rocks,

soil, water

🌎 An ecosystem is the

specific area where

these living and

nonliving things

interact

What are Feeding

Relationships

Organisms take on different

roles in an ecosystem, which

eventually form into feeding

relationships , or, who eats

whom?

We see these depicted in a

graphic organizer called a

Food Web. The different

types of roles displayed in the

food web are Producers and

Consumers.

What Are Producers?

🌎 There are also specialized

organisms in the bottom

depths of the oceans that

are also producers despite

having no access to

sunlight. They do this

through chemosynthesis, or

making their own food

from the chemicals that

come out of volcanic vents

within the ocean’s

trenches.

🌎 Producers

• are organisms that make their own food,

so photosynthetic plants and algae are producers.

What Else Are Consumers? 🌎^ They are ALL over the food web, existing as primary consumers through higher-order consumers - it just depends on what they

🌎 Decomposers - are are eating.

organisms that break down other organisms into basic elements and compounds.

What Else About

Consumers?

🌎 Consumers can also be divided into three other categories: ○ Herbivores - organisms that only eat plants (Herb = plant; Vore = to eat) ○ Carnivores - organisms that only eat meat (Carni = meat) ○ Omnivores - organisms that eat plants and meat (Omni = All)

What Are Other Forms of Relationships?

🌎 Other Relationships that Affect Ecosystems are: ○ Competition ○ Predator-Prey Relationships ○ Commensalism ○ Mutualism ○ Parasitism ○ Trophic Cascades

Competition 🌎 Watch the linked video on the next slide and pay attention to what specific resources animals compete for.

🌎 When two or more

organisms compete for the same resources

Examples of things animals compete for are… (type

in the 3 spots below).

Example 3:

prey

Example 2: water

Example 1: food

Predator-Prey

Relationships

🌎 A relationship where one animal hunts another. ○ Prey are the hunted. ○ Predators are the hunters. 🌎 Watch the linked video on the next slide and pay attention to how predators and prey both try to survive in their environments.

I wonder…(double click on the cloud and type a

question you have predator and prey relationships)

How many years take a species to evolve?

Commensalism,

Mutualism, and Parasitism

🌎 Each of these are a relationship between a “parasite” and a “host”.

🌎 All of them are beneficial for the parasite, but they have different for the host. ○ Commensalism - is neutral for the host ○ Mutualism - is beneficial for the host ○ Parasitism - is negative for the host

What did you like? What didn’t you like?

What was easy? What was hard?

Reflect on today’s activities:

It is straight to the point.

Commensalism,mutualism and parasitism.

I do not dislike anything.

Nothing really,but feeding relationships.
