Answer:
There is no video but ecological relationship will be defined on a general note and it is not always beneficial to organisms.
Explanation:
In an ecosystem, organisms of the same or different species tend to interact with one another. This interaction is referred to as ECOLOGICAL RELATIONSHIP between the involved organisms. An ecological relationship can be of different types depending on the effect.
SYMBIOSIS is an ecological relationship between two organisms that interact together. SYMBIOSIS can either be mutualistic (both organisms benefit), parasitic (one organism loses and one gains), or commensalistic (one organism benefits and one neither benefits or loses). Another ecological relationship is PREDATION, where one organism called the PREDATOR feeds on part or all of another organism called PREY in order to obtain energy.
As stated above, some of the organisms involved in an ecological relationship benefits while others lose. Hence, it is not always a beneficial relationship to organisms.
<span>Plants use carbon dioxide and sunlight to make their own food and grow the carbon becomes part of the plant. Plants that die and are buried may turn into fossil fuels made of carbon like coal and oil over millions of years. When humans burn fossil fuels most of the carbon quickly enters the atmosphere as carbon dioxide :) i love biology</span>
Answer:
The correct answer will be option-E
Explanation:
The soft cheese like Camembert, blue cheese and feta cheese are prepared from the unpasteurised milk.
Since the milk is not pasteurized therefore there are higher chances that the prepared cheese will have the micro-organism which could be lethal to humans like Listeria. Listeria is a bacteria which gets killed during the pasteurization process.
The pregnant woman should avoid eating the soft cheese as the cheese could contain the harmful bacteria like listeria which once ingested can enter the placenta and can kill the unborn babies or preterm delivery.
Thus, option-E is the correct answer.
I think it might be the third option but I’m not sure
