The Effects of Herbicides on Aquatic Organisms Anthony Cerda John Jay Science and Engineering Academy Abstract In this experiment different herbicides were added to aquatic organisms. The organisms used were protists and bacteria which are microscopic organisms (Microorganisms). Herbicides are chemicals used to control certain plants such as weeds. Two hypotheses were tested in the experiment.H₁) The herbicides will affect the population growth rate of the microorganisms and H₂) The adding

A number of slightly modified versions of chlorophyll exist. All photosynthetic organisms (plants‚ algae‚ prochlorobacteria‚ and cyanobacteria) have the form known as chlorophyll a. These organisms also contain other pigment molecules known as accessory pigments (see Table). Accessory pigments absorb energy not absorbed by chlorophyll a. Chlorophyll b

Historically the simple single celled organisms have sometimes been referred to as monads.[1] The main groups of unicellular organisms are bacteria‚ archaea‚ protozoa‚ unicellular algae and unicellular fungi. Unicellular organisms fall into two general categories: prokaryotic organisms and eukaryotic organisms.Unicellular organisms are believed to be the oldest form of life‚ possibly existing 3.8 billion years ago.[2] Prokaryotes

PROTIST STUDY GUIDE 1. Where can Protists primarily be found? Most Protists can be found in wet areas‚ tree trunks and other organisms 2. What niche do Protists fill in an ecosystem? Protists have a big role in marine life‚ it serves as housing for many animals and food for many as well. 3. What are the 3 categories of Protists? Animal-like protists plant-like protists and fungus-like protists 4. What are the 4 types of Protozoa and how does each one move? Ciliates : Have hundreds of

growth and subsequent death of algae‚ which reduces the dissolved oxygen available for other aquatic organisms. The main stages or steps of eutrophication are (in order): Nutrients wash into a river or stream. Algae grow quickly in response to the added nutrients. The algae block sunlight to aquatic plants‚ so photosynthesis slows‚ and less oxygen is released into the water - low DO levels. Decomposer populations increase because they have more food (the algae)‚ and they use up all the oxygen
