Biodiversity

The diversity of physical landscapes and its importance.

A larger strutural divseristy supports a larger biodiversity. More diversity of species the more sustainable and health of ecosyetem. It's adaptibility to viruses and diseases will greatly lower.

Tourism and forestrySources of natural medicationDisruption to biochemical cyclesThreatens food supplies

Predators prey on their preys for foodex. Cayote eating a rabbitHerbivores eating an plantBoneworms feed on the bones of a dead whale

Species protect another when needed the other organism for sheltor.ex. Hermit crabs us the shell of dead snails for sheltor and protection.

Species move from on place to another through the help of another species.Get carries by another speciesex. Flower mites are stuck on a dog and carries to another destination where they can reproduce.

Species depend on eachother fro reproductionSheltor to reproduceSpecial cases: Trillium seeds need ants to germinate

Some species help maintain the health of other speciesMutual relationshipCoral reefs have cleaning stations that help fishes clean external parasites

Species can help break down food in our digestive tracts.ex. Bacteria

Humans played a huge role in the diversity of species

EukaryotesMulticellularLive in terrestrial or aquatic environmentsNo cell wall or cytoplasmHeterotroph: Not make own food

Cell wall: Made of celluloseHave chloroplastAre autotrophsEukaryotes -> multicellularStationary

Eukaryotic , have nucleus and membrane bounded organellesLocomotion: Have cillia, flagella to move

Major producers in the aquatic ecosystem

StationaryMajor decomposersHeterotrophsHave different cells compared to plants: Hyphae composed of cytoplasm and many nuclei

Most diverse kingdomProkaryotes: Single celledLack nucleous: Have DNA

Prokaryotes: Single celledLive in extreme environments: Ex. Digestion tractsUnique genetic information

A discussion of rather living or non-living:Need a host cell to reproduceAdapt to environmentDon't grow or make their own/or use energyHave genetic information

A type of bacteria that attacks bateria

HIV, HPV, Covid 19

When a genetic information is transfered or given from a bacteria to another.

When the E.coli gets a toxic strand of genetic information from another bacteria. E.Coli only spreads the toxins when it is killed.

Causes antibiotic resistance.

when a bacteria picks up genetic information from their surrounding.

When proteins change, causing holes in the brain.

Eating infected cows, causing humans to get CJD.

Species can reproduce under natural circumstances

They can use energy for maintanence and growth.

Living things adapt to the environment.

Cells are organized at levels:Tissue: Organized cells to perfrom a taskOrgan: Organized tissues to perform a taskOrgan system: A group of organs performing a taskOrganism

Living things gorw through cell division and cell enlargement.

Classification allows scientists to better understand a species and can better communicate with other scientists on this species more effectvily.

The modern way of classifying species according to their ancestrial relationships.It can better distinguish species that looks very similar

A family tree used to show the connections and relationships between and among species.

An ancestor and all their descendents

The classification of species according to apprearence, behavior etc.
