Size: Adult males: 67ft long and weighing up to 56 long tons; 63 short tons.
Adaptation: one adaptation that they do have is their highly developed Echolocation,
which is a trait all toothed whales have. Echolocation, a high-pitched sound is sent out by the whale. The sound bounces off the object and some returns to the whale. The whale interprets this returning echo to determine the object’s shape, direction, distance, and texture.
Second adaptation is that the Sperm Whales have developed is their Brain size. The Sperm Whale has the largest brain of any animal to ever roam the earth. The Sperm Whale’s brain is on the average about 20 Lbs and is used quite often.
A third adaptation for Sperm whales is that they are the deepest diving whales. Although they live at the surface they dive to hunt giant squid that are bottom dwellers. Average dives are about 4,000feet deep. The Sperm whale can hold its breath for about an hour.
Yeasts are single-celled fungi.
Over 600 different species of yeast are known and they are widely distributed in nature. They are found in association with other microorganisms as part of the normal inhabitants of soil, vegetation, marine and other aqueous environments.
Some yeast species are also natural inhabitants of man and animals. While some species are highly specialized and found only in certain habitats at certain times of the year, other species are generalists and can be isolated from many different sources.
Habitat: The stereotypical image of ferns growing in moist shady woodland nooks is far from a complete picture of the habitats where ferns can be found growing. Fern species live in a wide variety of habitats, from remote mountain elevations, to dry desert rock faces, to bodies of water or in open fields. Ferns in general may be thought of as largely being specialists in marginal habitats, often succeeding in places where various environmental factors limit the success of flowering plants.
Adaptation (to the ecology): Many ferns depend on associations with mycorrhizal fungi. Many ferns only grow within specific pH ranges; for instance, the climbing fern (Lygodium palmatum) of eastern North America will only grow in moist, intensely acid soils, while the bulblet bladder fern (Cystopteris bulbifera), with an overlapping range, is only found on limestone.
Generation/life cycle: Ferns are vascular plants differing from lycophytes by having true leaves (megaphylls), which are often pinnate. They differ from seed plants (gymnosperms and angiosperms) in their mode of reproduction—lacking flowers and seeds. Like all other vascular plants, they have a life cycle referred to as alternation of generations.
Ecosystem is the whole system,… including not only the organism-complex, but also the whole complex of physical factors forming what we call the environment…”
An ecosystem consists of the biological community that occurs in some locale, and the physical and chemical factors that make up its non-living or abiotic environment. There are many examples of ecosystems -- a pond, a forest, an estuary, a grassland.
The study of ecosystems mainly consists of the study of certain processes that link the living, or biotic, components to the non-living, or abiotic, components. Energy transformations and biogeochemical cycling are the main processes that comprise the field of ecosystem ecology.
There are many different ecosystems: rain forests and tundra, coral reefs and ponds, grasslands and deserts. Climate differences from place to place largely determine the types of ecosystems we see.
