Chapter 6 Biology

what is the difference between an organism's habitat and its niche

A habitat is the place where an organism lives and a niche is the organism's role in that environment

Symbiosis

A particularly close, interdependent relationship between two species

competitive exclusion principle

Ecological rule that states that no two species can occupy the same exact niche in the same habitat at the same time

pioneer species

First species to populate an area during primary succession

There is a growing concern over the decline in the US honeybee population due to the use of pesticides. how could a reduced honey bee population affect biodiversity and ecosystems services? design a solution for this problem

Well if honey bees are gone many plant populations would eventually die and be gone and then animals that eat those plants would be affected too. A solution would be to use less pesticides on crops/flower bees pollinate

A polar bear and a grizzly bear live in very different biomes. Based on this information can you conclude that the microbiomes inside their intestines are also very different from each other? Explain your reasoning.

Yes, they are very different because their microbiomes inside them respond to their outside environment, diet, and lifestyle traits.

ecosystem services

are the benefits provided by ecosystems to humans.

which term describes the variety of species in a certain area?

biodiversity

A salt marsh that helps prevent flooding of a coastal town is an example of what ecosystem service?

buffering

How is commensalism different from mutualism?

commensalism is where an organism is benefiting and the other one is neither helped nor harmed. and mutualism is where two species both benefit.

Biodiversity

defined as the variety and varibility of animals, plants, and microorganisms

Niche

describes where an organism lives and what it does for a living.

Microhabitats

examining environmental conditions on a smaller scale will reveal the microhabitats for organisms

ecological succession

gradual change in living communities that follows a disturbance

Mutualism

is a symbiotic relationship between two species in which they both benefit.

Commensalism

is a symbiotic relationship in which one organism benefits and the other is neither helped nor harmed

Parasitism

is a symbiotic relationship in which one organism lives inside of or on another organism and harms it.

resource

is any necessity a species needs to live, and differs for each species

resilience

natural ability to recover after a disturbance

secondary succession

occurs when a disturbance affects an existing community but doesn't completely destroying it

The first organism to repopulate an area affected by volcanic eruption are called

pioneer species

keystone species

plays a vital an unique role in maintaining structure, stability, and diversity in an ecosystem

what determines whether ecological succession is classified a primary succession or secondary succession

primary succession occurs in an environment without previous life, or a barren habitat, begins in a lifeless area. Primary succession is ecological succession

describe the 2 major types of ecological succession?

primary succession: begins on newly formed rock or areas with no remnants of older communities Secondary succession: occurs when a disturbance affects an existing community but doesn't completely destroy it.

genetic diversity

refers to the total of all different froms of genes present in a particular species.

What is an ecosystem service? list an example

regulation of floods. An ecosystem service is any positive benefit that wildlife or ecosystems provide to people

primary succession

succession that occurs on surfaces where no soil exists

how is species diversity different from genetic diversity

the difference between animals of the same species

what is most likely to happen if an organism's environment is outside the organism's range of tolerance

the growth of the organism's increase

habitat

the natural HOME or environment of an animal, plant, or other organism.

how can different species of insect-eating bugs live in the same tree

they will hunt for their prey in different parts of the same tree, and they will also be most likely eat different bugs.

Tolerance

variety of environmental conditions in which it can survive and reproduce.

ecosystem diversity

variety of habitats, living communities, and ecological processes in the living world

What describes the resilience of an ecosystem? Include an example of resilience

Inherent ability to absorb various disturbances and reorganize while undergoing state changes to maintain critical functions.

Microbiomes

Microbiomes are microscopic communities too small for our eyes to comprehend. The organisms existing in these tiny habitats perform various functions.

what is competitive exclusion principle

No 2 species can occupy the same niche in the exactly the same habitat at the exact same time.

How is parasitism different from other types of symbiosis

There are 3 types of symbiosis and parasitism is different because an organism benefits by then the other organism is severely harmed or could die

species diversity

The number and relative abundance of species in a biological community.

What is often the end result of secondary succession

The result is called a climax community. Parts of the community still exist.
