Answer:
Positive affect" refers to one’s propensity to experience positive emotions and interact with others and with life’s challenges in a positive way. Conversely, "negative affect" involves experiencing the world in a more negative way, feeling negative emotions and more negativity in relationships and surroundings.
These two states are independent of one another, though related; someone can be high in positive and negative affect, high in just one, or low in both. Both states affect our lives in many ways, particularly when it comes to stress and how we handle it.

4- Sponges have the ability to regenerate when they are separated into pieces
Plants and animals live in interacting, interwined communities. There is a characteristic set of species in different environments. For example, certain species of trees, shrubs, ground cover, arthropods, reptiles, mammals, birds etc. live in a temperate forest environment. A completely different set of creatures live in a marsh, or a grassland or an agroecosystem. However, the relationships between these groups can be defined by the ecological role they play, the flow of energy between them and the cycling of nutrients between them. This is a fancy way of saying "everything is connected"! And if you change one part of the system, something else changes. In an ecosystem management decision, you hope you know what those consequences of your actions are!) This is important in managing agroecosystems as well.
