Answer:
Fusarium oxysporum is a fungus which obstructes xylematic ducts in the tomato plant and causes necrosis in the ploem of the plant.
Explanation:
The xylem in a plant is made up of differentiated cells, this cell system performs apoptosis so that the dead cells form a structure called the xylematic ducts. And so it gives way to the creation of a system through which the absorption of water from the soil will be carried out until it reaches the leaves of the plant. What fusarium does when colonizing the xylematic ducts, is to cover them, obstruct them and in this way is that this fungus prevents the absorption of water for the leaves of the plant.
The ploem is another structure in the plant. The phloem has the function of transporting the nutrients made by photosynthesis to those parts of the plant that cannot perform this process that are usually located in the basal or underground part. this will generate that there is no adequate passage of nutrients for the whole plant and its subsequent wilting.

Answer:
If the producer population decreased, the size of the hervibores population will diminish.
Explanation:
Producer population refers to autotrophic organisms (plants for example). These organisms are the nutrition source for primary consumers (like hervibores). So if the nutrition source decreased, the population size of hervibores will decreased too.
