1) Animals must have either wings or limbs adapted for movement on a hard surface.

2) The outer integument adapts to temperature changes.

3) Plants and animals in arid habitats have adaptations for obtaining, storing, and economically using water.

4) The presence of bright colors and aroma for pollination.

In the ground-air environment:

a) excess oxygen

b) lack of oxygen

c) excess water

d) lack of water

• In the ground-air environment, you can move on the ground and…
• There are significant fluctuations in the ground-air environment...
• There is enough oxygen in the ground-air environment, but often not enough...

• What animal is encrypted in the rebus?
• Give him a description according to plan:

• unicellular or multicellular;
• Which kingdom does it belong to?
• what habitat does it occupy?
• How is it adapted to this environment?

Aquatic life environment

All aquatic inhabitants, despite differences in lifestyle, must be adapted to the main features of their environment. These features are determined primarily by the physical properties of water: its density, thermal conductivity, and ability to dissolve salts and gases.

Ground-air environment of life .

This environment has a different set of features. It is generally more complex and varied than aquatic. It has a lot of oxygen, a lot of light, sharper temperature changes in time and space, significantly weaker pressure drops and moisture deficiency often occurs.

Soil as a living environment .

Soil is a thin layer of land surface, processed by the activity of living beings. Solid particles are permeated in the soil with pores and cavities, filled partly with water and partly with air, so small aquatic organisms can also inhabit the soil. The volume of small cavities in the soil is a very important characteristic of it. In loose soils it can be up to 70%, and in dense soils it can be about 20%.

Living organisms as a living environment.

Examples and additional information

In the aquatic environment, the living conditions of its inhabitants vary greatly in different parts of the reservoir. Eternal darkness reigns in the depths of the oceans. There's a lot of pressure here. In deep depressions it is a thousand times greater than on the surface of the Earth. The bottom has a constant low temperature of about -2 °C and low oxygen content. Only microorganisms and some animals live here. In the upper layers of seas and oceans, the water is permeated with light, aerated, its temperature changes throughout the year, algae live in it and photosynthesis occurs.

“Habitat of organisms” - Characteristics of environments. Water environment. Habitat – conditions surrounding an organism. What kingdoms of organisms do you know? Lesson conclusions: Each organism is adapted to life in a certain environment. Adaptations to aquatic habitats. Wings, limbs for moving on a hard surface, wool, feathers, devices for economical consumption of moisture, devices for pollinating plants.

“Habitat” - Inhabitants of the ground and air environment - aerobionts. Water environment. Inhabitants of the aquatic environment are hydrobionts. Habitat (environment). Study of different habitats of organisms. Aquatic habitat. Place the animals or plants from the list provided in the appropriate habitat. Basic living environments.

“Soil habitat” - Ground-air environment. Underdeveloped eyes and ears. The mycelium of mushrooms is also located here, Short fur (for less friction with the soil). Special mouth structure (so that soil does not get in). Powerful front teeth (for digging and biting roots). Plant roots. Animals are depicted here. Secretion of mucus (promotes movement in the soil).

“Habitat of Polar Bears” - Roar of a bear. Video of a brown bear. The habitat of polar bears is the Arctic. Bears feed on fish and seals. Polar bear. Females are noticeably smaller (200-300kg). Kulkova Olga. Habitat and appearance. The polar bear is the largest terrestrial representative of mammals of the order of carnivores.

“Adaptation of organisms to the environment” - Limits of acceptable levels. Classification of space flight factors. Characteristics of the survival of animals at an altitude of 12 km at different times of the day (A) and different times of the year (B). The effect of weightlessness on the body. Daily rhythm. Adaptation of the body and habitat. Classification of biorhythms. Average duration of some rhythmic ones.

“Educational environment of the school” - Creativity. Organization of the teacher's workplace. It is framed and open in nature. For all subsequent stages of training. Mastering work in a unified information environment. Independence. Mastering the means of digital photo and video recording. Multimedia environments for child-adult interaction. Initial retraining in the field of ICT competence of primary school teachers.
