in what way are heterotrophs dependent on photosynthesis by autotrophs (explain at a 6th grade level)

2 answers:

6 0

Hello! Autotrophs make their own food (plants) and heterotrophs consume other organisms for energy (consumers.) Autotrophs use the process of photosynthesis to produce the oxygen as one of its products. Heterotrophs use the oxygen produced by the autotrophs to perform cellular respiration, which releases carbon dioxide that plants use; it's a balanced cycle. Hope this helps!

Plants are referred to as autotrophs. Auto– means "self," and in this case, –troph means "feeding." Autotrophs are those organisms that make their own food. All plants are autotrophs, and so are algae and many bacteria. Organisms that are unable to produce glucose through photosynthesis are called heterotrophs. Heterotrophs obtain organic food molecules for energy and nutrition by eating other organisms or by eating and absorbing by-products of other organisms.

How is enthalpy used to predict whether a reaction is endothermic or exothermic?

Radda [10]

Answer:

$329.48 KJ/mol$ heat is released by the combustion of $2 mol$ of methane

Explanation:

The value of enthalpy determines whether the reaction is exothermic or endothermic. If the enthalpy change is positive, then the reaction is endothermic (heat or energy released) and if the enthalpy change is negative then the reaction is exothermic (heat or energy absorbed).

$2CH_4(g)+4O_2(g) => 2CO_2(g)+4H_2O(g)$

$\Delta H \ reaction=[ 2(\Delta HfCO_2)+ 4(\Delta HfH_2O)]-[2(\Delta HfCH_4)+4(\Delta HfO_2)]$

= $2 ( -(393.5 KJ)/mol)-[2( -74.6 KJ/mol)+4(-241.82 KJ/mol)]$

$= -787 KJ/mol-[ -149.2 KJ/mol-967.28 KJ/mol]$

$= -787 KJ/mol+1116.48 KJ/mol$

$=329.48 KJ/mol$

In this question, the enthalpy of formation has positive value and hence the reaction is endothermic in which the heat is released.

A group of scientists is studying the internal parts of a cell. Which microscope is most appropriate for these scientists to use

Lady bird [3.3K]

The most appropriate microscope for studying the internal parts of the cell is ELECTRON MICROSCOPE. The correct option is B.
Electron microscope, which is a compound microscope is usually used to study the internal environment of the cell because of the easiness with which one can easily distinguish the cell organelles from one another. Electron microscope gives great clarification of the cellular components and allow scientists to observe minute details about cellular structures. Electron microscope usually magnify specimens to one million times of their real sizes.

svet-max [94.6K]

Answer:

Names are universal

Explanation:

Current naming system that is followed all over the world is called binomial nomenclature. There are many significant and useful features of this classification system however one of the most important feature is the universality of the name.

The scientific names of organism are usually Latin derived and composed of two parts among which first is genus name and second is specie name.

For example: Rosa indica is the scientific name of Rose and it is same all over the world. Unlike common names we dont have to search for name to make others understand which flower we are talking about because if we know scientific name anyone can understand it.

Hope it help!
