Algae and Phycology

Frogs will eat as many mayflies as it can catch. A very good protein source.

A number :)

Algae can get nitrogen from poop or animal waste

(it absorbs it by the way) make sure that if you want to feed algae you give it light and warm water, because it grows better in summer than winter. here is the website that my friend's mom found http://fcps.edu/islandcreekes/ecology/green_algae.htm

Algae grows on rocks because they provide a stable surface for attachment, access to sunlight for photosynthesis, and nutrients in the water for growth. Algae can secrete substances that help them adhere to rocks and compete for space and resources with other organisms.

Blue-green algae or Cyanophyceae uses photosynthesis to create food. The genus is called Oscillatoria. They are closely related to bacteria.

fungi protects the algal partner from stronge light and desiccation in this way it gets food by the coutesy of alga.

no its a producer

Yes, they do; symbiont green algae are called zoochlorellae.

Not long if they land on me, horrid tickly things.

This is a tricky one to ask as there are around 4,400 different types of greenfly and, as one might expect, there is some degree of variation in the lifespan of different types. It's also worth remembering that a greenfly is only one stage of the insect we call an aphid's life - it spends time as a nymph (pre-adult) and as an egg (in most cases - unusually for an insect, some species can produce live young).

The common greenfly we see in the UK is called Brevicoryne brassicae, the cabbage aphid. Nymphs hatch from eggs after about a week to 12 days. The time the individual then takes to develop into the adult greenfly then probably depends more on environmental factors than time - ie, availability of food, temperature etc. However, once it does, a female will be able to produce young for around a month at a rate of five or six per day, after which she will die. I've been unable to find any similar data for male aphids - but "about six weeks" seems a reasonable answer to your question.

Here's some interesting greenfly facts: Greenfly can reproduce asexually - that is, a female does not need a male in order to produce young. They've been around for about 280 million years, far longer than humans have. Ants farm aphids in much the same way that we farm cows - the ants collect a sticky substance known as honeydew which made by the aphids and in return protect them from predators. Greenfly often travel vast distances on wind currents - individuals marked in the UK have been found as far away as Russia.

Algae is a eukaryotic plant, its cells contain chloroplasts.

rocks, limestone, animals, ice, trees, water, springs, soil, trees

The useful effects of algae is that it provides oxygen for various living things. Algae is also a food resource for humans and fish.

Algae can become harmful if they produce toxins. Too much algae in the water can kill fish because the algae consumes a great amount of oxygen and can block the sunlight from reaching underwater.

phytoplankton

zooplankton

meroplankton

holoplankton

Any of various chiefly aquatic, eukaryotic, photosynthetic organisms, ranging in size from single-celled forms to the giant kelp. Algae were once considered to be plants but are now classified separately because they lack true roots, stems, leaves, and embryos.

No, some are filamentous or even with false branching. But in most of the algae their gametes are motile, having flagella.

At one time cyanobacteria were called blue-green algae and were included with the algae. However, like bacteria and unlike algae, cyanobacteria are prokaryotes, meaning that they do not have a nucleus. For this reason they were removed from the algae (which are eukaryotes) and put into the bacteria, with all the other prokaryotes. See: http://www.ucmp.berkeley.edu/bacteria/cyanomm.html http://fig.cox.miami.edu/Faculty/Dana/cyano.html

Red algae is found in all regions of the world. They are attached to the bottom or other hard surfaces, and are often most conspicious in the intertidal region of rocky coasts and in tide pools.

diffeent colours such as green, blue green, yellow and red algae

Large groups of green algae:

Diatoms

Chlorophyta

Euglenophyta

Dinoflagellata

Chrysophyta:

Phaeophyta:

Rhodophyta

Cyanobacteria

The algae converts energy from sunlight using photosynthesis. The tadpole eats the algae and incorporates approx. 1/10th of its energy. The heron eats the tadpole and converts approx. 1/10th of its energy, giving it 1/100th of the original energy.

All living things are biotic factors.

So bugs can eat it.

I believe you are talking about carrageenan, which is a gel-like substance that comes from a species of red algae called Irish moss. It is used as a thickening agent, not necessarily to emulsify ice cream. It is also used in evaporated milk and some pharmaceutical agents as well. :-)
