Слайд 2 Special features of formation and population of the forest ecosystems.
The main producers are trees, there are a lot of
econiches in these ecosystems, dominate detrital food chains with four or less chain links.Circulation of substances is slowed down.
Слайд 3The forest ecosystems.
In the broad-leaved forest plant-feeders (elks, hares,
deers, roes and a great number of insects) eat only
7-10 % of organic production, no more.
Слайд 4The State of Texas (USA), State of the Lonely Star
Natural symbols: a flower - Bluebonnet (literally it is translated
as a dark blue hood) - dark blue- purple, from a type of lupines, and the bird-Moskinbirds-mocker, armadillo.
Слайд 5The State of Texas (USA), State of the Lonely Star
In the east and the southeast savannas the oak and
pine woods remained.The pine woods with impurity of an oak, ficuses, low palm trees, everything is intertwined with evergreen lianas.
Слайд 6The State of Texas (USA), State of the Lonely Star
The most numerous animals are coyotes deer and armadillos.
Слайд 7 Special features of formation and population of fresh-water ecosystems.
The producers are organisms of fitoplankton - algas (green and
diatomic) and tsianobakteriya. 
Слайд 8The fresh-water ecosystem.
. In lakes value of the large
plants called macrofits is great. Makrofits are as water plants
(duckweeds, water-lilies, jugs), and coastal water - "amphibians" (a cane, a horsetail, a reed).
Слайд 9The fresh-water ecosystem.
The main consumers in water ecosystems are
zooplankton –phytophagous (cladocerans, e.g. daphnids) and sarcophagous, (e.g. copepods Cyclops).
Слайд 10The fresh-water ecosystem.
The fish that form nekton. Among the
fish there are
phytophages, zoophages and euryphages, and very often
fish “tastes” are changing with age. 
Слайд 11The fresh-water ecosystem.
Many birds such as different species of
ducks, seagulls, long-legged, sandpipers, and dabchicks also belong to the
consumers of water ecosystems.mammals (beaver, muskrat, mink, and otter).
Слайд 12The fresh-water ecosystem.
Amphibians (newt, frog, fire-bellied toad) and
reptiles (fresh-water turtle, water snake).
Слайд 13The fresh-water ecosystem.
The number of links in the food
chain of a lake can amount to six. Three links
of the plankton food chain (algae – phytophagous plankton – sarcophagous plankton) is added by three links of nekton (e.g. roach, perch, pike).
Слайд 14The fresh-water ecosystem.
The matter cycle in freshwater ecosystems is fast
and is measured in months rather than years.
Слайд 15The State of Texas (USA), State of the Lonely Star
There are several natural lakes and hundreds of man-made ones
in Texas. 
Слайд 16The State of Texas (USA), State of the Lonely Star
The biggest rivers in Texas are Red River, Trinity, Brothers,
Colorado and Rio Grande; a large number of small rivers in the central and western parts often dry up.
Слайд 17The State of Texas (USA), State of the Lonely Star
The state of Texas is an annual transient home for
great numbers of migrant birds; it guarantees winter habitation for almost all local bird species.
