Question: In an ecosystem, predation is a biological interaction where a predator (an organism that is hunting) feeds on its prey (the organism that is attacked). Predators may or may not kill their prey prior to feeding on them, but the act of predation often results in the death of the prey and the eventual absorption of the prey's tissue through consumption. Thus predation is often, though not always, carnivory. Other categories of consumption are herbivory (eating parts of plants), fungivory (eating parts of fungi), and detritivory (the consumption of dead organic material (detritus)). All these consumption categories fall under the rubric of consumer-resource systems. It can often be difficult to separate various types of feeding behaviors. For example, some parasitic species prey on a host organism and then lay their eggs on it for their offspring to feed on it while it continues to live in or on its decaying corpse after it has died. The key characteristic of predation however is the predator's direct impact on the prey population. On the other hand, detritivores simply eat dead organic material arising from the decay of dead individuals and have no direct impact on the "donor" organism(s).
Try to answer this question if possible: A species that uses a host body to survive and reproduce is classified as a what?
Answer: parasitic species
Question: The great angiosperm radiation, when a great diversity of angiosperms appears in the fossil record, occurred in the mid-Cretaceous (approximately 100 million years ago). However, a study in 2007 estimated that the division of the five most recent (the genus Ceratophyllum, the family Chloranthaceae, the eudicots, the magnoliids, and the monocots) of the eight main groups occurred around 140 million years ago. By the late Cretaceous, angiosperms appear to have dominated environments formerly occupied by ferns and cycadophytes, but large canopy-forming trees replaced conifers as the dominant trees only close to the end of the Cretaceous 66 million years ago or even later, at the beginning of the Tertiary. The radiation of herbaceous angiosperms occurred much later. Yet, many fossil plants recognizable as belonging to modern families (including beech, oak, maple, and magnolia) had already appeared by the late Cretaceous.
Try to answer this question if possible: When had eight main groups of Chloranthaceae recognizable as belonging to modern families appear?
Answer: unanswerable
Question: On June 16, 1988, 6,000 to 8,000 people gathered in Lviv to hear speakers declare no confidence in the local list of delegates to the 19th Communist Party conference, to begin on June 29. On June 21, a rally in Lviv attracted 50,000 people who had heard about a revised delegate list. Authorities attempted to disperse the rally in front of Druzhba Stadium. On July 7, 10,000 to 20,000 people witnessed the launch of the Democratic Front to Promote Perestroika. On July 17, a group of 10,000 gathered in the village Zarvanytsia for Millennium services celebrated by Ukrainian Greek-Catholic Bishop Pavlo Vasylyk. The militia tried to disperse attendees, but it turned out to be the largest gathering of Ukrainian Catholics since Stalin outlawed the Church in 1946. On August 4, which came to be known as "Bloody Thursday," local authorities violently suppressed a demonstration organized by the Democratic Front to Promote Perestroika. Forty-one people were detained, fined, or sentenced to 15 days of administrative arrest. On September 1, local authorities violently displaced 5,000 students at a public meeting lacking official permission at Ivan Franko State University.
Try to answer this question if possible: Who tried to stop the rally?
Answer: Authorities
