The former means those most fit, those with the best set of skills and features for the given environment, will live to pass on the said features in the offspring (with ants, for example, being incredibly fit and adaptable creatures). The latter suggests there is an objective way to measure the "meaningfulness" of each species and having only those most meaningful survive. But this differs from species to species - for a house cat, the great white shark is utterly meaningless.
Also, the meaningful animal has no actual advantage over another to help him survive, whereas fittness is exactly that - it is the ability to survive, ability to pass on your genes.
While I understand it may seem so in the case of domestic animals that the most meaningful to the human are those allowed to reproduce, it is actually the same law: those most adapted for human purpose (which, of course, in the given case means the most meaningful) ARE the fittest here in the human-controlled environment.
Firstly, we need to know what a healthy ecosystem is. When an ecosystem is healthy, this would mean that it could supply all the resources that all organisms present in it and with all the resources, there is diversity. Old growth forests are considered healthy because of this reason. These forests remain untouched and had remained in providing the resources needed for the organisms present in it.
ELECTRON MICROSCOPES USE A BEAM OF ELECTRONS INSTEAD OF LIGHT TO MAGNIFY IMAGES
Answer:
These equipment limit children opportunities to experience diverse and active childhood experiences.
Explanation:
Parts of child basic developmental psychology is socialization through interaction with different environments of diverse objects and individuals. This stimulate brain developments, builds child's confidence, approach and allow movements from one location to another. However, fixed piece equipment which although may provide rooms for slight skeletal exercises,do not allow interaction with other infants in diverse environments, and this limit exposure to diverse and active childhood experiences.
It is called inter specific competition
