<span>food chains follow just one path of energy as animals find food.

</span>food webs show how plants and animals are involved in ways to help them all survive.

Answer & Explanation: Food chains show the feeding relationships between species in a biotic (living) community. Food webs are diagrams showing the organisms that eat other organisms in a particular ecosystem with predators being higher in the web than their prey. While a food chain only follows just one path as animals find food, a food web is a collection of many food chains, showing the many different paths plants and animals are interconnected.

Describe how the functional units for beta carotene, xanthophyll, chlorophyll a, and chlorophyll b are different. be sure to ide
leonid [27]

The pigments have a similar structure of 40 carbon atoms covalently bonded in a chain. Carotenoids contain oxygen atoms in their chemical structure (retinyl functional group) while xanthophyll does not. This makes carotenoids more non-polar compared to xanthophylls, hence move farthest in chromatography paper using a nonpolar mobile phase. Chlorophyll pigment, on the other hand, has chlorin rings (which are larger) as functional units hence move slowly in chromatography.

Photosynthetic rates can be measured by either the amount of oxygen they consume per particular time period or the amount of carbon dioxide produced per particular time period. This is conducted while immersed in water so as to measure bubble rate formation in case of oxygen production or the change in water pH in the case of carbon dioxide consumption.

When autumn approaches, the amount sunlight received by the plant is reduced due to longer night than days. Deciduous trees have adapted by losing chlorophyll a and b pigments (most important in photosynthesis) during this time. This leaves a higher amount of the other red and yellow pigments hence making the leaves change from green to yellow-red.

It is believed that this is the result of an ancient endosymbiotic relationship between a protist and a eukaryotic cell. The protist generates energy that the eukaryotic can utilize in its growth and reproduction while the protist is sheltered. This relationship became obligatory symbiosis over time.

Organisms that live in the _________ must be adapted to little or no rain and to extreme temperatures.
umka21 [38]

Answer: DESERT

Explanation:

Adaptation can be defined as the modification in the form, structure, function and behaviour of organisms in a habitat which enables them to live successfully and reproduce.

Desert is one of the types of the world biomes that is characterized with little or no rain and to extreme temperatures. Organisms, which includes plants and animals, must show some level of adaptation to able to survive the harsh environment.

The type of PLANTS which can survive in desert environment are called the XEROPHYTES. They show the following adaptations:

--> The roots are well developed: they grow down to great depths and branch extensively in order to absorb water

--> they possess swollen stems which contains water storage cells.

--> they have reduced leaves, for example in cacti in the form of spines, which helps to reduce water loss through transpiration.

The type of animal that survive in desert environment spend the hot dry seasons in a sleep-like torpid state called aestivation. This is so in order to avoid the heat. Their body size is usually small and less bulky: greater surface area in relation to body volume, thus enhancing heat loss from the body.

Organisms that live in the _________ must be adapted to little or no rain and to extreme temperatures.
