Ecology
|
Ecology is the concept of how living things relate, connect, and sustain in their environment.
|
|
What are the five levels Ecology
|
The first level and base is “descriptive ecology.” Descriptive ecology is the connection between living things and the habitats in which they exist in. The second level is “comparative ecology.” Comparative ecology is observing and analyzing the common concepts of the earth but also comparing the unlike ideas between nature and the earth. “Casual ecology” is the third level of the pyramid; it is the understanding of why something happens because of another thing, it is result. The fourth level is “experimental ecology,” that consists of the several experiments scientist use to create possible solutions to draw conclusions about the earth. The fifth and final level is the “theoretical ecology.” The theoretical ecology is where individuals study the environment to gives details and ideas about how the earth functions.
|
|
Biotic Factors
|
All the living organisms in the environment and their effects, both direct and indirect on other living things.
|
|
Ecosystem
|
The community and the nonliving environment interact to form an ecological system
|
|
Abiotic Factors
|
Means without life and affects ecological interactions
|
|
Autotrophs
|
The lowest level of producers
|
|
Herbivores
|
only plants (phototrophs) and are first level consumers
|
|
Carnivores
|
eat other animals
|
|
Predators
|
attack and kill their prey and are second level or higher consumers
|
|
Scavengers
|
eat dead animals they find
|
|
Omnivores
|
: eat both plants and animals
|
|
Decomposers
|
down the remains of dead plants and animals
|
|
Estuary
|
is a semi-closed body of water found along a coast that is open to the sea and receives a flow of fresh water from the surrounding watershed.
|
|
Watershed
|
is the land area that drains into a particular body of water
|
|
Niche
|
the role of a species in an ecosystem
|
|
Habitat
|
the area or environment where an organism or ecological community normally lives or occurs
|
|
Symbiotic Relationships
|
relationships in which two different organisms live in close association to the benefit of one or both (There are three types)
|
|
Three types of Symbiotic Relationships
|
Mutualism: both organisms benefit
Commensalism: one benefits and the other is not affected Eating and apple off a tree Parasitism: one benefits and the other is harmed Tapeworm |
|
Food web
|
Interconnected food chain
|
|
Producers
|
organism that create their own food molecules through the process of photosynthesis
|
|
Consumers
|
organisms that eat other organisms to obtain energy-rich molecules that they break down chemically to obtain the energy required to build tissue and maintain life.
|
|
Four levels of consumers
|
Primary Consumers-Herbivores animals that eat produces
Secondary Consumer-Herbivore-eating Carnivores Tertiary Consumers- Carnivore-eating carnivores Quaternary Consumers-higher level carnivore eating carnivores |
|
Biomagnifications
|
The process by which such successively higher concentrations of the substances accumulate in living tissues
|
|
Limiting factors
|
Environmental factors that affect the growth, abundance, and distribution of a population or organism
|
|
Deadwood
|
If we want ecosystems around us, then we need to keep dead trees, because they are important to different organisms.
|
|
Warming World
|
The more global warming we have, the more likely do organisms and phonological changes alter. Ecosystems rely on each other; without one playing its part, the other cannot either.
|
|
Leave No Child Inside
|
The more that children are active and outside, the more they learn and are able to remember things and be impacted.
|
|
Meat Guzzler
|
How much meat Americans consuming is being taken for granted.
|
|

Relationship between organisms and their environment
Biosphere-life on earth Ecosystem- all organisms in the river Community-striped salmon in the river Population-all striped salmon Organism-salmon Organ System-circulatory system Organ-liver Tissue-muscle Cell-blood cells |
|
Abiotic Component on Calvin’s campus is--- that affects the biotic component that is ---
|
Abiotic Component on Calvin’s campus is light that affects the biotic component that is plants. The amount of sunlight in MI will help the plants die or grow on campus

|
|
The greater the niche overlap between two species the more intense the competition can be for limited resources-explain
|
If two species are living in same environment with the same characteristics, then they will compete and both struggle each day to survive. (Survival of the fittest)

Given a scenario be able to decide which management strategy is the best to use:
Community Government Private Ownership Know the type of Management took place in the book of Acts Community |
|
Water Treatment Plant
|
Scrapers (organic or non)
1.Sand Settles 2.Fats float on top scum off top and sludge off bottom 3.Micro-organisms added 4.Air Bubbles Oxygen makes bugs hungry 5.Centrifuge Bugs go to center, clean water goes to outside 6.UV light sterilizes viruses 7.Pumps water to the river |
|
Can this process be found in nature
|
1.Branches that fall in river
2.Lakes, curves on river, deep areas 3.Not found in nature 4.In water 5.Not found in nature Bugs don’t get to eat phosphate 6.Occurs in nature, left on its own, we just speed it up in plant 7.Not found in nature |
